There s subchondral sclerosis in the acetabulum with osteophyte formation indicating developing osteoarthritis. The right femoral head appears sclerotic but has preserved normal contours. Appearances are suspicious for avascular necrosis here also. The medulla of the left femoral diaphysis has a striated appearance. There are no definite features to suggest medullary infarcts. Knee joint unremarkable.
There are changes of avascular necrosis present involving the articular and subarticular portion of the humeral head.
Case Discussion
Steroid induced avascular necrosis is present as a result of prior treatment for AML.
