Findings
There is subchondral geographical area of altered signal intensity involving anterosuperior portion of both right and left femoral head lined by hypointense rim (double-line sign) - suggestive of avascular necrosis. It involves <25% of articular surfaces. The infarcted region shows fibrosis signal appearing hypointense on T1W and T2W images relative to the normal marrow (Mitchell class D).
Early degenerative changes are seen in both hip joints.
No evidence of subchondral collapse or fracture.
Bilateral superior hip joint space is mildly reduced.
