Showing AVN of humeral heads and vertebral changes

Radiology case 38--651 Clinical presentation: There are two cases, each in a young woman of African ancestry. The condition is an inherited anaemia with recurrent episodes that can affect many body systems.
There is biconcave narrowing of the vertebral bodies. The depressions in the end-plates are squared. The bone density is...

comminuted fracture of the distal humerus
* due to direct trauma (elbow in car window hits approaching vehicle)

"unicameral" or "solitary" bone cyst
* lytic, unilocular
* central
* meta-diaphyseal
* humerus (most common site)
* age 0 - 10 yrs
DDx: bubbly bone lesions

Radiology case 415-3181 Female aged 5 years, X-rayed after a fall, apparently symptomless.
There is a lytic lesion in the upper metaphysis of the left humerus. There are visible septa that make the lesion appear multiloculate, although it is probably uniloculate. The lesion thins the cortex from below, but there is...

Radiology case 443-3181 4 year old boy, complaining of pain in the left hip.
There is a lobulated lytic lesion that expands the upper metaphysis of the left femur. The lesion is crossed by strands of dense bone that give it a multiloculate appearance. The endosteal margin of the lesion is...

Radiology case 462-3181 Clinical presentation: Follow up view after a previous fracture in a 16 year old male.
The skeleton is immature. The fibular lesion is cyst-like with a well defined endosteal margin. It expands the bone, but does not breach the cortex. The long axis of the lesion is parallel to...

Radiology case 4642-3181 20 year old woman with sudden onset of pain in the right ankle, which prevented her from standing on that leg.
Lateral and oblique views show an area of low bone density in the calcaneum, greater and denser than the normal variant. It has a sclerotic, well-defined and...

contusion and subsequent tendonitis in the proximal attachment of the patellar tendon
* can be followed by calcification, ossification, or frank inferior pole avulsion fractures that produce one or more distinct ossicles.
per Stedman's dictionary: "apophysitis of the distal pole of the patella"
symptoms:
* tenderness and soft tissue swelling over the lower...

Radiology case 448-3143 Clinical presentation: 83 yr old female with increasing pain and deformity.
The view shows multiple irregular small areas of bone loss, particularly in the pubis on both sides of the pelvis. The pathology extends to the ischium on the right side and into the whole of the ischium on...

Although many dysplasias are quite rare, some occur with sufficient frequency that most general practice radiologists will see them and should know something about them. This chapter gives an extremely simplified meatball approach to the diagnosis of these more common disorders. You won't find rare syndromes such as bird-headed dwarvism...

Radiology case 443-4146 Clinical presentation: Male aged 13 years. There is no recorded history of obesity or particularly active pursuits. The femoral neck is not lined up with the curve of the left acetabulum, the left epiphysis is shortened and displaced backwards and is projected infero-medially in this view. The left epiphysis...

* boys> girls
* age 10 - 15 yrs
* blacks> whites (unlike CHD + Legg-Perthes disease)
* related to height, weight, athletic activity
* if BILATERAL ==> renal osteodystrophy
* femoral epiphysis slips POSTERIORLY and MEDIALLY
* use frog-leg + lateral projections
* complications:
  o AVN
  o acute cartilage necrosis (chondrolysis)
  o varus deformity

Radiology case 439-362 Clinical presentation: 14 year old boy with a general abnormality.
There is a greater separation of the heads of the metacarpals of the index and middle fingers of the left hand. Increased soft-tissue and a round, well-circumscribed calcific density lie between the 2 and 3rd metacarpals. There is a...

* There is an expansile, lucent, well-defined ("geographic") lesion with swirls and rings of chondroid calcification at the base of the proximal phalanx of the right 4th digit.
* Pathologic fracture is present.
Findings are compatible with a benign solitary enchondroma of bone.
