A 58-year-old man presented with a seizure and loss of consciousness. Neuroimaging revealed a highly vascularized 5.7 x 5 cm solid mass in his right temporo-parietal region. Biopsy determined the mass was a solid supratentorial hemangioblastoma, a rare tumor. Further tests ruled out Von Hippel-Lindau disease. The patient underwent partial resection of the mass, improving his symptoms. Solid supratentorial hemangioblastomas occurring as single lesions unrelated to Von Hippel-Lindau disease are infrequent and atypical clinical presentations like this case are rarely reported.
The document discusses medulloblastoma, a type of brain tumor that occurs most often in children. It arises from primitive cells located in the cerebellum. Key points include that surgery is usually the first treatment, but radiation therapy plays a central role in improving survival. Treatment may involve craniospinal irradiation with a boost to the tumor site. Prognosis depends on factors like age and extent of disease. Long term side effects can include neurological and endocrine issues due to radiation therapy.

The document provides information about brain metastasis including:
- Brain metastasis are cancer cells that have spread to the brain from primary tumors elsewhere in the body. Lung cancer, breast cancer, melanoma, and renal cancer are common sources.
- Symptoms depend on the location of metastases and can include headaches, nausea, focal weakness, seizures, and alterations in consciousness. Diagnosis is typically made through MRI or CT imaging.
- Treatment involves steroids, anticonvulsants, surgery to remove solitary metastases, stereotactic radiosurgery for a small number of lesions, whole brain radiation, and occasionally chemotherapy. The prognosis is generally poor with a median survival of 4-5 months.
This document discusses brain biopsies, including their history, indications, and procedure. Brain biopsies are used to determine the cause of diffuse or multifocal brain diseases when the specific diagnosis cannot be established by other means. Key indications include infections, vasculitides, pediatric neurodegenerative diseases, and atypical dementias. The procedure involves making a burr hole in the skull under general anesthesia and removing a small sample of brain tissue for analysis. Potential complications include hemorrhage, swelling, neurological deficits, seizures, and infections. A multidisciplinary team approach is recommended for planning and evaluating brain biopsies.
Intradural extramedullary mass - a case on MRIREKHAKHARE
An 18-year-old boy presented with 6 months of lower back pain and lower extremity weakness on the left side. MRI revealed two masses - an intradural extramedullary mass between D10-D12 deviating the spinal cord to the right, and a long paravertebral mass extending from T7-L1. The intradural mass enhanced with contrast and was considered to be an intradural extramedullary lesion such as a neurofibroma. The patient was referred for surgical management and biopsy to determine the exact diagnosis.
The document summarizes various tumors and lesions that can occur in the cerebellopontine angle (CPA). The most common tumors are acoustic neuromas (schwannomas), which arise from the vestibular nerve. Other lesions include meningiomas, metastases, epidermoid tumors, dermoid cysts and lipomas. Imaging plays an important role in the diagnosis and treatment depends on the type and size of the lesion.
Pineal gland is essentially an extra axial midline structure lying at the roof of dienchephalon rostral to the quadrigeminal cistern surrounded by important neurovascular structure, occurring in the geometric center of brain with same depth of trajectory had made the surgery in this region a formidable challenge to neurosurgeons, however radical resection must be the goal in selected pathologies, if not pure germ cell tumor.
This document discusses craniospinal irradiation (CSI) techniques. It defines CSI as radiation delivered to the entire cranial-spinal axis. The document outlines the indications for CSI including various types of brain tumors. It then discusses the challenges of CSI due to the large irregular target volume and proximity to critical structures. The document focuses on the 3D conformal technique in supine position used at the author's department. It describes patient positioning, immobilization, simulation, target and organ at risk delineation, and treatment planning. Complications of CSI and the role of chemotherapy are also reviewed. Alternative CSI techniques like IMRT and proton therapy are mentioned but have limitations. Dosimetric studies find modern
This document provides information on brain tumors including:
- Brain tumors can be benign or malignant and originate in the brain or spread there from other areas. Common types include glioblastomas and meningiomas.
- Symptoms depend on the tumor's location but can include headaches, seizures, and neurological deficits. Diagnosis involves imaging like CT/MRI along with biopsy.
- Treatment options include surgery, chemotherapy, and radiation therapy. The goal of surgery is maximal tumor resection while preserving brain function. Other therapies are used as adjuvants or for inoperable tumors.
This document summarizes the diagnosis and treatment of intramedullary spinal cord metastasis (ISCM). ISCM is rare, accounting for 0.9-2.1% of cancer metastases, with the most common primary sites being lung, breast, and colon cancers. MRI with gadolinium is the best diagnostic tool. While no randomized trials have been done, retrospective studies suggest that surgery combined with radiation therapy can improve neurologic function and survival compared to radiation alone. Stereotactic radiosurgery is a promising alternative to traditional radiation and has shown improved neurologic outcomes in some cases with fewer side effects. Overall prognosis remains poor, with 80% mortality within 3 months for most patients.
This document summarizes information about intracranial tumors. It discusses their etiology, clinical features, classification, diagnosis and treatment. The major types of tumors covered include gliomas, meningiomas, acoustic neuromas, metastatic tumors and pituitary tumors. Gliomas form about 50% of adult primary intracranial tumors and arise from glial cells. Meningiomas are most often benign and originate from the meningothelial cells of the arachnoid villi. Acoustic neuromas arise from Schwann cells of the 8th cranial nerve. Metastatic tumors commonly originate from the lung, breast and kidney and are diagnosed via imaging. Pituitary tumors account for about 8%
Cranial surgery involves procedures to access and treat conditions within the skull and brain. The main types discussed are burr holes, craniotomies, and craniectomies. Craniotomies provide larger access than burr holes and are used for procedures like tumor removal, hemorrhage evacuation, and repairing vascular structures. Craniectomies involve removing a piece of skull that is later reconstructed. Additional topics covered include cranial procedures for vascular conditions like aneurysms, skull base surgery, and treating tumors, infections, hydrocephalus and more. Precise techniques and equipment are needed to perform surgeries near vital structures in the brain.
Medulloblastomas are the most common malignant brain tumors in children. They arise in the cerebellum and can spread through the CSF pathways. Complete surgical resection followed by craniospinal irradiation is the main treatment approach. CSI provides improved local and systemic tumor control compared to other radiation techniques based on early studies. Medulloblastomas are highly radiosensitive tumors, making radiation an important part of management, though younger patients and those with residual disease or metastasis have poorer outcomes.
This document describes the case of an 8-year-old boy who presented with 6 months of headaches and 1 month of gait disturbance. After examination, MRI revealed a posterior fossa midline neoplastic lesion involving the right cerebellum and compressing the fourth ventricle, causing hydrocephalus. The diagnosis was medulloblastoma with hydrocephalus. The patient underwent VP shunt placement for hydrocephalus and then midline suboccipital craniectomy for tumor resection. Outcomes and complications of the surgery are discussed.
This document discusses various types of brain and spinal tumors. It covers topics such as:
- Common types of brain tumors including meningiomas, acoustic neuromas, pituitary adenomas, gliomas, and medulloblastomas.
- Diagnostic tests for brain tumors including MRI and specialized blood tests.
- Treatment options for different tumor types including surgery, radiation, chemotherapy, and radiosurgery.
- Differences in tumor locations and characteristics between adult and childhood brain tumors.
- Types of spinal cord tumors and their characteristics.
This document provides an overview of brain tumors including their definition, causes, risk factors, classification, symptoms, diagnostic tests, treatment options and nursing management. Some key points:
- A brain tumor is an abnormal cell growth within the brain that can be benign or malignant. Common types include gliomas, meningiomas, and pituitary tumors.
- Risk factors include age, gender, family history, exposure to radiation or chemicals. Symptoms vary based on tumor location but may include headaches, nausea, vision changes, seizures and neurological deficits.
- Diagnosis involves imaging tests like CT/MRI along with biopsy. Treatment options include surgery, radiation, chemotherapy, and supportive care. Nursing focuses on monitoring for increased

La hemorragia subdural aguda espontánea es rara y puede deberse a factores como hipertensión o anomalías vasculares. Se presenta el caso de un paciente con esta afección tratado mediante una hemicraneotomía osteoplástica que permitió evacuar completamente la sangre y controlar el sangrado, con una buena recuperación del paciente. La craneotomía en este tipo de hemorragias ofrece una amplia exposición quirúrgica para drenar la sangre y reducir la presión intracraneal.
La lamina cuadrigemina, también conocida como los tubérculos cuadrigeminos, es una estructura en el mesocefalo que interviene en numerosos reflejos visuales y auditivos. Está compuesta de cuatro eminencias de sustancia gris y blanca. Sus conexiones aferentes y eferentes le permiten integrar información sensorial y motora, controlando funciones como la fijación ocular, los movimientos de la cabeza y los ojos, y la respuesta al sonido.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

5. Brain Hemangioblastoma
It is a rare neoplastic entity of the Central Nervous
System.
On 2016, classification for CNS tumors of WHO
classifies this type of lesion as a non-meningothelial
mesenchymal tumor grade 1.
It is a highly vascularized lesion, whose most frequent
differential diagnosis is Arteriovenous Malformations
and lesions with cystic component in a large number of
cases confirmed by Scientific publications.
6. Frequently associated with Von Hippel Lindau disease
These lesions are commonly located in the posterior
fossa, they constitute 2% of all intracranial tumors.
They preferentially affect the cerebellum, spinal cord,
and brainstem.
Its location in the supratentorial space is less than
0.5% of the cases reported.
7. The location of these lesions in the
supratentorial space in their solid form,
not associated with VHL disease, is
extremely rare; cases with these
characteristics have not been frequently
reported, at least in the publications on
the subject during the last decade. .
8. We present the case of a 51-year-old patient with a
history of high blood pressure with regular
treatment.
Was treated in our center for presented symptoms
of loss of consciousness for approximately 40 min
and involuntary movement. (Generalized tonic
clonic seizures)
Initially received in the ICU service, where was
performed Intensive Treatment with the objective
of preserve his live getting recovery his state
concious
9. Neuroimaging studies were performed in
order to establish a definitive diagnosis in
the patient.
Brain Contrast CT Scan
Brain Contrast MRI
10. The contrast Brain CT Scan study reports the presence of a
conglomerate of vessels on right temporal, parietal and occpital
region measuring 5.7 x 5 cm that is nourished by the branches
of the right middle cerebral artery, associated with brain edema
that collapses and displaces the ventricular system to the left 1
cm.
17. Posterior parietal craneotomy was performed
with the aim of obtaining biopsy and achieving a
maximum safe resection of the tumor
(50% of the lession was removed)
18.
19. Microscopic study
Cytoplasm cells loaded with lipids that form
the stroma
Capillary vessels without nervous tissue

Mast cells
20. . Other imaging studies were performed during the
postoperative period :
• Abdominal Ultrasound (USD)
• Lung CT
• MRI of the Spine
A fundus eye examination was performed
21.
22.
23. Post-surgical status of the patient at 72
hours.
• Sensory dysphasia
• No motor deficit
• Glasgow Coma Scale 14/15 points
24. The final diagnosis was determined by
biopsy, Image study and clinical
correlation as solid supratentorial
hemangioblastoma not associated with
VHL
