Avascular Necrosis of the Hip
64 y/o man with left hip pain
The left hip shows the "double-line sign" that is characteristic of AVN; a hypointense line adjacent to a hyperintense line.
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.
