CT scan of Rib pathologies
This article discusses various pathologies that can involve the ribs, including congenital, neoplastic, infectious, metabolic, and inflammatory disorders. CT is useful for characterizing rib lesions seen on other imaging and can reveal underlying systemic diseases or primary cancers. Key rib pathologies discussed are lymphangiomatosis, metastases, Pancoast tumors, Gorham disease, chondrosarcoma, enchondroma, fibrous dysplasia, aneurysmal bone cyst, septic arthritis, Paget's disease, gout, and ankylosing spondylitis. CT findings may include bone expansion or erosion, calcifications, soft tissue masses, and periosteal reactions depending on the specific disease.
Rare Bone Tumors 2
This document summarizes several rare bone tumors and bone disorders:
- Fibrous dysplasia is a developmental anomaly that appears on x-ray as a cystic lesion with a ground glass appearance. Treatment involves curettage, grafting, and fixation.
- Melorheostosis causes sclerotic bone lesions that look like dripping wax on x-rays. Symptoms typically develop by age 20.
- Osteopoikilosis is a rare, autosomal dominant disorder causing multiple small areas of increased bone density without symptoms.
- Aneurysmal bone cysts appear on x-rays as radiolucent lesions with an expanded cortex arising in the bone's medullary canal, causing

This document provides a summary of various joint diseases and conditions as seen on radiographs. It compares and contrasts osteoarthritis and rheumatoid arthritis, describing features such as joint space narrowing, erosion, and subchondral sclerosis. Infectious arthritis, septic arthritis, and Charcot joints are also summarized. Avascular necrosis, Perthes' disease, slipped capital femoral epiphysis, and developmental dysplasia of the hips are discussed along with their characteristic radiographic findings.
Melorheostosis
1. Melorheostosis is a rare sclerosing bone disorder of unknown cause that produces thickened bone along the surface and inner lining of bones.
2. It most commonly affects the lower extremities in individuals between 5-20 years old and presents with bone overgrowth patterns resembling candle wax or myositis ossificans on imaging.
3. Affected individuals may experience pain, joint stiffness, deformities, and leg length discrepancies. Skin thickening and vascular abnormalities can also occur.
Bones and joints
The document discusses various bone and joint disorders including:
1. Achondroplasia and osteopetrosis, which cause short stature and skeletal abnormalities due to defects in bone growth and remodeling.
2. Mucopolysaccharidoses and type I collagen diseases affect cartilage and bone development, resulting in short stature and skeletal deformities.
3. Hyperparathyroidism causes increased bone resorption and cystic lesions in bones.
4. Renal osteodystrophy in chronic kidney disease leads to bone abnormalities from mineralization defects.
5. Rickets and osteomalacia involve inadequate bone mineralization causing weak, fragile bones.

Diseases of bone and its oral aspects
Dr. Gaurav S. Salunkhe presented on oral and maxillofacial pathology. The document discussed the classification, development, diseases and conditions that affect bone, including the alveolar bone. Specific conditions discussed in detail include cherubism, osteogenesis imperfecta, osteopetrosis, and cleidocranial dysplasia. Cherubism is a rare hereditary condition causing bilateral jaw swelling in children that typically resolves after puberty.
Pathology of fibro osseous lesions
Fibrous dysplasia is a benign fibro-osseous lesion caused by a mutation in the GNAS1 gene. It involves the replacement of normal bone by fibrous tissue and irregularly shaped trabeculae of woven bone. Common sites are the craniofacial bones. Cherubism is a related condition restricted to the jaws, caused by SH3BP2 mutations. Ossifying fibroma is a benign neoplasm composed of cellular fibrous tissue with variably sized calcified deposits. Differential diagnosis includes Paget's disease, osteosarcoma, and other fibro-osseous lesions.

Fibroosseous lesions
This document provides information on fibro-osseous lesions. It begins with definitions and classifications of fibro-osseous lesions. It then focuses on fibrous dysplasia, the most common fibro-osseous lesion. Fibrous dysplasia is a skeletal developmental anomaly caused by a mutation that results in abnormal bone formation. It can be monostotic, affecting a single bone, or polyostotic, affecting multiple bones. Radiographs show poorly defined lesions blending into normal bone with abnormal trabeculae. Histologically, there is replacement of bone by proliferating fibrous tissue and irregular bony trabeculae.
Bone degenerative disorders
The document discusses several bone disorders and degenerative conditions, including osteoporosis, osteomalacia, rickets, osteomyelitis, tuberculosis osteomyelitis, syphilitic osteomyelitis, and Paget's disease.

Bone pathology
This document discusses fibrous dysplasia and cemento-osseous dysplasia, two fibro-osseous lesions of bone. It covers the classification, etiology, clinical features, radiographic appearance, histopathology, and treatment of these conditions. Specifically, it describes how fibrous dysplasia is caused by a mutation leading to overproduction of cAMP, and can present as monostotic or polyostotic lesions. It also outlines the three types of cemento-osseous dysplasia - focal, periapical, and florid - based on clinical and radiographic characteristics.
Fibro osseous lesion
Fibrous dysplasia is a disease characterized by replacement of normal bone with fibrous tissue containing abnormal bone formation. It is caused by a mutation that leads to overproduction of cAMP in affected tissues, disrupting bone maturation. There are three main types: monostotic (single bone), polyostotic (multiple bones), and craniofacial. Clinical features include bone pain, swelling, and deformity. Radiographs show abnormal bone patterns ranging from radiolucent to sclerotic "ground glass" appearance. Complications can include fractures, deformity, and in rare cases McCune-Albright syndrome with additional endocrine abnormalities.
Approach to generalised increased bone density
- Intramembranous ossification involves mesenchymal cells differentiating directly into osteoblasts and forming bone, while endochondral ossification involves cartilage models that are later replaced by bone.
- Dysplasias of ossification can involve failures in resorption and remodeling of primary spongiosa (endochondral) or intramembranous bone, leading to accumulation of unresorbed cartilage or bone.
- Metabolic bone diseases like renal osteodystrophy involve abnormalities of calcium and phosphate metabolism from chronic kidney disease, leading to osteomalacia, secondary hyperparathyroidism, and bone lesions.
Skeletal dysplasia : Radiodiagnosis
A number of skeletal dysplasia are covered in this ppt with basic information and radiographic images.
Diseases of bones and joint
The document discusses diseases of bone, including developmental disorders. It describes four developmental disorders:
1. Cherubism - A rare jaw condition seen in childhood characterized by bilateral swelling of the jaws due to fibrous dysplasia-like lesions. It is caused by a genetic mutation and lesions typically regress after puberty.
2. Osteopetrosis - A rare disease caused by a defect in bone remodeling resulting in abnormally dense bone that is fragile. It can cause anemia, fractures, and nerve compression.
3. Osteogenesis imperfecta - The most common inherited bone disorder caused by collagen defects, characterized by bone fragility and fractures that easily heal. Other features include blue sclera
Skeletal dysplasia
This document discusses skeletal dysplasias (osteochondrodysplasias), which are disorders involving abnormalities of bone or cartilage growth and texture. It describes the classification of skeletal dysplasias into four groups based on their anatomical location and characteristics. Key radiographic features of several common skeletal dysplasias are outlined, including spondyloepiphyseal dysplasia congenita (SEDC), spondyloepiphyseal dysplasia tarda (SEDT), multiple epiphyseal dysplasia (MED), pseudoachondroplasia, chondrodysplasia punctata (CDP), mucopolysaccharidoses (MPS), Morquio syndrome
Bone Cancer
The exact cause of primary bone cancer is not fully understood but the researchers believe that it is caused by over-activity of the bone cells. Studies have shown that there is a much higher risk of bone cancer in those persons, who had taken radiotherapy or chemotherapy with alkylating anticancer drugs during their childhood. Pain and swelling are the most common symptoms of bone cancer.

Introduction of fibroosseous lesions
This document discusses fibro-osseous lesions and cherubism. It notes that fibro-osseous lesions involve the replacement of normal bone with collagen fibers and fibroblasts containing mineralized substance like bone or cementum. Cherubism is described as a benign hereditary condition of the maxilla and/or mandible seen in children under 5, causing fullness of the jaws and cheeks with upward gaze. Cherubism is usually autosomal dominant but with varying penetrance between males and females.
Imaging in rickets
Rickets is a childhood bone disease caused by vitamin D deficiency and impaired bone mineralization. Symptoms include bone pain, soft tissue swelling, and bone deformities. Radiographically, rickets is characterized by widened growth plates with irregular and frayed metaphyseal margins, cupping of the metaphysis, and generalized osteopenia. Specific findings include craniotabes, bowing deformities of the long bones, rib fractures causing a "rachitic rosary" appearance, and triradiate pelvis. The document provides detailed radiological descriptions and images of findings in rickets.

Silicosis
Silicosis is caused by inhalation of dust containing silica, and the risk depends on particle size, exposure duration, and individual susceptibility. It manifests as chronic (after 10+ years), accelerated (5-10 years), or acute (weeks/months) forms. Workers at risk include miners, pottery/ceramic workers, metal grinders, sand blasters, and construction workers. Upon inhalation, silica particles are engulfed by macrophages, causing inflammation and fibrosis that appears as nodules in the lung's upper zones. Symptoms include cough, shortness of breath, and chest pain. Diagnosis is via chest X-ray and pulmonary function tests. Treatment focuses on removing exposure

Orthopedic Aspects Of Metabolic Bone Disease By Xiu
This document summarizes various metabolic bone diseases and their orthopedic manifestations and radiographic findings. It covers osteoporosis, rickets and osteomalacia, hyperparathyroidism, hypoparathyroidism, hyperthyroidism, and renal osteodystrophy. For each condition, it describes clinical presentation, pathogenesis, characteristic radiographic findings including areas of bone involvement and patterns of bone changes, and differential diagnoses.
Osteopetrosis
This document discusses osteopetrosis, also known as marble bone disease, which is a rare hereditary disorder characterized by defective osteoclast function that results in abnormally dense and brittle bones. There are two subtypes: infantile autosomal recessive osteopetrosis, which is more severe and often fatal in childhood, and autosomal dominant osteopetrosis, which is less severe and allows survival into adulthood. The document describes the clinical features, radiographic findings, differential diagnoses, and key features that distinguish osteopetrosis from similar conditions like pyknodysostosis and melorheostosis.

Seronegative spondyloarthropathies
This document discusses seronegative spondyloarthropathies, which are musculoskeletal syndromes linked by common features including being negative for rheumatoid factor and often involving the axial skeleton. There are five main subgroups, including ankylosing spondylitis, psoriatic arthritis, reactive arthritis, enteropathic arthritis, and undifferentiated spondyloarthritis. The document then provides details on the clinical presentation and radiographic findings for each of these three conditions in three sample patient cases.
Joint X-Ray
This document provides an overview of various imaging modalities used in rheumatology and describes the characteristic radiographic findings of common rheumatic diseases including osteoarthritis, rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, gout, and pseudogout. Key radiographic features of each condition such as erosions, osteophytes, periosteal reactions, and patterns of joint involvement are discussed. The importance of understanding these imaging findings to help diagnose rheumatic conditions is emphasized.
Arthritis and arthroplasty- dr. Mahmoud Abdel Kareem
This document provides information about osteoarthritis (OA), including its definition, prevalence, risk factors, pathology, diagnosis, natural history, differential diagnosis, and treatment. It notes that OA is the most common form of arthritis, affecting over 20 million people in the US. Risk factors include age, obesity, family history, and previous joint injury or disorder. Diagnosis is typically based on symptoms like pain and stiffness, physical exam findings, and x-ray evidence of cartilage loss, bone spurs, and bone changes. Treatment includes conservative options like medications, exercise, and weight loss, as well as intra-articular injections or surgery for advanced cases.
Radiology 5th year, 3rd lecture (Dr. Salah Mohammad Fatih)
This document discusses various bone and joint diseases and their radiological features. It covers rickets and osteomalacia, noting their effects on bone mineralization and growth plates. Hyperparathyroidism is discussed as causing decreased bone density and subperiosteal bone resorption. Paget's disease causes thickening of bone trabeculae and cortex, leading to bone enlargement. Hemolytic anemias like thalassemia can cause bone marrow hyperplasia seen as thinning cortices and prominent trabeculae. Radiation exposure may lead to osteonecrosis, osteoporosis or sarcomatous changes. Osteoarthritis is characterized by joint space narrowing and subchondral
Radiology of Bone Tumours
This document provides information on classifying primary bone tumors based on location and radiographic appearance. Key points include:
- Location within the bone (epiphyseal, diaphyseal, metaphyseal) and age of the patient help classify tumors.
- Features like margins, extent of bone destruction/formation, and presence of a matrix provide clues about tissue type and aggressiveness.
- Common sites for different tumors are listed to aid diagnosis.
- Patterns of bone destruction (lytic, motheaten) and periosteal reactions further characterize lesions.
Osteomyelitis of jaw--department of oral medicine and radiology
Osteomyelitis of jaw--department of oral medicine and radiologyGovernment Dental College and Hospital, Shimla
The document discusses osteomyelitis, which is an inflammatory condition of bone that begins as an infection of the medullary cavity and spreads to involve the periosteum. It can be acute or chronic, and is caused by bacteria or fungi entering via trauma or a blood-borne route. Symptoms include pain, swelling, and pus drainage. Diagnosis involves medical imaging and biopsy. Treatment involves antibiotics, drainage of pus, debridement of infected tissue, and sometimes surgery. Chronic osteomyelitis can be difficult to treat and may require repeated surgeries. Risk factors include reduced blood supply to bone from conditions like diabetes.Xray bone-tumor
Location and age of the patient are important for classifying primary bone tumors. Certain tumors have preferences for specific bone locations, such as the proximal femur for chondroblastoma or distal femur for osteochondroma. The appearance on x-ray including margin characteristics, degree of bone destruction or formation, and presence of a matrix can provide clues to the tissue type and likelihood of being benign or malignant. Aggressive lesions with indistinct margins carry a higher risk of malignancy.

Bone forming tumors rabins
This document discusses osteoid osteoma, a relatively common benign bone tumor. It is characterized by a small nidus less than 1.5 cm in diameter that typically causes persistent night pain relieved by salicylates. Diagnosis is usually made through imaging like CT or MRI that identify the central nidus. Treatment options include long-term anti-inflammatories, percutaneous radiofrequency ablation to destroy the nidus, or surgical removal of the nidus through curettage or en bloc resection. The document also briefly discusses other bone forming tumors like osteoblastoma, osteoma, and their signs, symptoms, diagnosis and treatment.

radRounds Weekly Radiology Rounds
A 4-year-old female presented with left knee pain and swelling for one year. Imaging showed a lytic lesion with sclerotic borders near the physis. MRI revealed decreased T1 signal, fluid signal centrally, and an enhancing rim, consistent with an abscess. Intraoperative curettage confirmed the diagnosis of Brodie's abscess, a localized form of osteomyelitis presenting as a well-circumscribed bone destruction surrounded by reactive sclerosis. Brodie's abscess is usually caused by hematogenous spread of bacteria like Staphylococcus aureus to the bone.
Radiology Rounds 29 Year Old S
A 29 year old patient presented with fluid in the abdomen after a fall. A cystogram was performed to better define a possible bladder injury and showed intraperitoneal contrast from the cystogram, indicating a bladder rupture where urine had leaked into the abdominal cavity. The dome of the bladder is the least supported area and often the location of intraperitoneal bladder ruptures from a sudden increase in pressure in a full bladder.
Radiology Rounds 56 Year Old With Elbow Pain
This document summarizes an anatomical variant called an avian spur or supracondylar process of the humerus. It is a bony projection found in 1% of the population that may represent a remnant structure from prehistoric humans. While usually asymptomatic, it can occasionally cause median nerve compression and symptoms like carpal tunnel if the ligament connecting it to the elbow is compressed. The document provides details on imaging findings, demographics, clinical presentation, and proposed evolutionary origin of this anatomical structure.
Radiology Rounds 57 Yo Male In Icu
This document discusses the differences between portal venous gas and biliary tract gas seen on imaging of the liver. Portal venous gas is usually caused by ischemic bowel and requires urgent surgery, while biliary tract gas is often associated with biliary-enteric fistulas or procedures. The location and transient nature of the air can help distinguish between the two, with portal venous gas appearing peripherally and dissipating over hours, while biliary tract gas remains more centrally located.
Radiology Rounds 71 Year Old Female,
A 71-year-old female presented with an aortic dissection. Her doctor noted an incidental vascular finding on imaging and requested the radiologist look again if necessary to identify any anomalous blood vessels. The radiologist found a partial anomalous pulmonary venous return (PAPVR) where blood was flowing from the lungs into the brachiocephalic vein rather than the left superior vena cava, creating a left-to-right shunt that could overload the right side of the heart by mixing oxygenated and deoxygenated blood.
Left Neck Pain
Radiology Rounds - CT of head/neck. Patient presents with left neck pain. This case was kindly provided by Dr. Laura Avery of Harvard Medical School, Massachusetts General Hospital to be postde on radRounds.com - Education, Social, and Professional Networking for Radiology.
Radiology Rounds: Retroperitoneal Bleeds
The document discusses the anatomy of the retroperitoneum and presents two case studies. It notes that blood from an aortic rupture would be expected in the posterior para-renal space, while blood from a retroperitoneal bleed would be located in the anterior para-renal space. The second case involves a patient on anticoagulation with expansion of the iliopsoas muscle and active bleeding from a small vessel, rather than an aortic leak.
Radiology Rounds: Pain After Fall
The document discusses signs that indicate a supracondylar fracture of the elbow in children, including:
- The "sail sign" where the anterior fat pad is displaced superiorly, giving away the fracture.
- The posterior fat pad becoming visible on x-ray as it is displaced from the olecranon fossa.
- The anterior humeral line intersecting the anterior third of the capitellum rather than the middle third, indicating the fracture.
Complications of these fractures include cubitus varus (angled elbow), vascular injury to the brachial artery, and Volkmann contracture limiting forearm function. A mnemonic "CRITOE" can help remember the typical order and
Radiology Rounds: Neck Pain After Trauma
This document discusses neck pain after trauma, specifically a hangman's fracture or traumatic spondylolisthesis of the axis (C2 vertebra). It notes disruption of the spinolaminar line at C2 on C3, indicating a fracture of the pars interarticularis of C2. It provides details on the anatomy of C2 including that it is the only vertebra with a pars interarticularis and discusses the mechanism of injury for a hangman's fracture, typically forceful hyperextension of the already extended neck.
Radiology Rounds: Elderly male with leg pain
The elderly male patient is experiencing leg pain due to Paget's disease affecting his femur. Radiology findings include cortical thickening, trabecular thickening, and increased bone size. There is also an incomplete fracture present. Paget's disease leads to pathological changes in bone including a destructive or active phase, combined destructive and proliferative phase, and final sclerotic phase, usually beginning at one end of the bone. Complications can include fractures or sarcoma.
Radiology Rounds: 62 year old male with pain after fall
A 62-year-old male presented with heel pain after falling from a ladder. Imaging of the lumbar spine revealed an L1 compression fracture. Calcaneus fractures due to falls from heights are sometimes bilateral and associated with compression fractures of the lumbar or dorsal spine in up to 10% of cases. The Bohler angle is used to assess calcaneus fractures, with a decreased angle indicating an intra-articular fracture and a poorer prognosis.
Radiology Rounds: 40 year old female with left flank pain
A 40-year-old female presented with left flank pain. Imaging showed delayed enhancement of the left kidney, cortical medullary nephrographic, and perinephric fluid, indicating possible calyceal rupture or obstructing calculus. The three most common locations for urinary tract stones are the ureteropelvic junction, pelvic brim, and ureterovesical junction. Treatment depends on stone size, with stones 4 mm or smaller likely to pass spontaneously and those larger than 8 mm unlikely to without intervention, while stones between 5-8 mm often pass with medical expulsive therapy.

Radiology Rounds: 25 year old man status post motor vehicle accident
A 25-year old patient presented with left hip pain after a motor vehicle accident. Posterior wall fractures of the acetabulum are the most common type of acetabular fracture, involving the posterior articular surface, rim, and column. These fractures often result from dashboard impacts and cause transient posterior dislocations of the hip. Follow up imaging with Judet views is needed to best evaluate fractures of the anterior and posterior walls and columns.
Neck Pain After Trauma
This document discusses neck pain after trauma, specifically a hangman's fracture or traumatic spondylolisthesis of the axis (C2 vertebra). It notes disruption of the spinolaminar line at C2 on C3, indicating a fracture of the pars interarticularis of C2. It provides details on the anatomy of C2 including that it is the only vertebra with a pars interarticularis and helps provide rotation, and discusses the mechanism of injury being hyperextension forces on an already extended neck.

What are the different types of Dental implants.
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.
