2. CHAPTER 36 :
Periostal Reaction; Bone and Joint Infections; Sarcoid
• Periosteal New Bone
• Infection
• Sarcoidosis
• Rare Bone Infections
• Brucellosis
• Actinomyosis
• Hydatid Disease (Echinococcus)
3. larval stage
the liver and lung
richly vascularized areas vertebrae and long bones
spine
adulthood
no pathognomonic
Less than 2% of affected patients is bone involved
Sheep farming areas
4.
5. well-defined, multiloculated osteolytic lesion
uncommon
The enlarging cysts in bone absorb trabeculae, spread along the medulla, thinning the cortex, expanding
the bone
Later, the cystic lesions become well defined, fibrous dysplasia may be simulated in long bones
6. best method
• Aneurysmal bone cyst, giant cell tumor and fibrous dysplasia

14. Giant CellTumor Aneurysmal Bone Cyst Fibrous dysplasia
• Lesion with multinucleated
giant cells
• GCT is also included in the
differential diagnosis of an ill-
defined osteolytic lesion,
provided the age and the site
of the lesion are compatible.
Discriminators :
• Epiphyses must be closed
• Must be an epiphyseal lesion and
abut the articular surface
• Must be well-defined and non-
sclerotic margin
• Must be eccentric
• Solitary expansile well-
defined osteolytic bone
lesion, filled with blood
• ABC can occur almost
anywhere in the skeleton
Discriminators :
• Must be under age 30
• Must be expansile
• In general FD is lytic and well-
defined, but can look like
almost anything
• FD may also contain cystic
parts, calcifications and
ossifications
• Mostly found in children and
young adults, but sometimes
as coincidental finding at older
ages
