Avascular Necrosis of the Hips

Unknown Musculoskeletal Case 1


Presentation

44 y/o man with history of steroid use for Crohn's Disease

Image Findings

The left hip shows the "double-line sign" that is characteristic of AVN; a hypointense line adjacent to a hyperintense line. The right hip shows extensive hypodensity and deformity of the femoral head in keeping with sclerosis and mild subchondral collapse.

Discussion

Avascular necrosis is secondary to vascular obstruction and commonly involves the hips. Predisposing conditions to AVN include steroid use as in this case, pancreatitis, alcoholism, sickle cell disease, rheumatoid arthritis, and systemic lupus erythematosis.
