title: Congenital Bimelic Hypertrophy of the Hands.
abstract: Congenital hypertrophy of the hand is a rare phenomenon. The condition is characterized by hypertrophy of muscles, varies in severity and has been reported under different names. Some patients also have aberrant muscles. Electromyography is unremarkable, and the signal intensity on MRI and ultrasound is normal. The etiology is unknown and does not seem to be confined to a peripheral nerve, part of the plexus or nerve root. The condition is assumed to be congenital. We report a 28-year-old male with asymmetric hypertrophy of both hands and give a review of the 4 other cases known so far.
