title: Avascular necrosis of femoral heads post-adrenal surgery for Cushing's syndrome: a rare presentation.
abstract: Avascular necrosis (AVN) is a well-recognized complication of patients on high-dose steroids for a long time. Exogenous hypercortisolism is a well known cause of AVN and a number of cases have been reported. Cushing's syndrome describes hypercortisolism of any cause endogenous or exogenous. A variety of traumatic and non-traumatic factors contribute to the aetiology of AVN although exogenous glucocorticoids administration and alcoholism are among the most common non-traumatic causes. AVN secondary to endogenous hypercortisolism is rare and very few case reports are available describing this complication. No literature is available on AVN presenting post-adrenal surgery. Here we present a young woman who presented with avascular necrosis of both hips 1 year after adrenalectomy for Cushing's syndrome.
