Abstract

Isolated musculocutaneous neuropathy is frequently associated with superior truncus lesions of brachial plexus and appears rarely. Musculocutaneous nerve palsy may occur in two patterns: proximal and distal injury. Proximal injury may cause motor and sensory deficits, but distal injury primarily causes sensory deficits. In our patient, neurologic symptoms were insignificant and electrophysiologic methods were very helpful for locating the lesion. Herein, we report a case of isolated distal branch musculocutaneous nerve injury with very occult clinical symptoms that resulted from a surgical procedure.
