Avascular Necrosis of the Hip


Presentation

34 y/o man with a history of hip dislocation

Image Findings

The RIGHT hip shows the "double-line sign" that is characteristic of AVN; a hypointense line adjacent to a hyperintense line.

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.
