Peroneal nerve palsy in anorexia nervosa.

Abstract

Central nervous system abnormalities are recognized complications of anorexia nervosa. However, peripheral nerve disorders are less well documented in this condition. We report 2 cases of peroneal nerve palsy in anorectic patients who had a tendency to spend long periods of time sitting cross-legged. The respective roles of mechanical compression and malnutrition in the pathogenesis of peroneal nerve palsy in anorexia nervosa are discussed.
