摘　　要：BACKGROUND Isolated musculocutaneous nerve injury is a rare condition.Herein,we report the first case of bilateral musculocutaneous neuropathy after vigorous stretching of both upper extremities with normal results of sensory nerve action potential.Clinicians should be aware of this rare condition that can appear bilaterally.In addition,the interpretation of the aberrant electrodiagnostic study results of this case was discussed.CASE SUMMARY A 29-year-old male complaining of bilateral forearm tingling and upper extremity weakness visited the outpatient clinic.The symptoms began 6 mo prior,and he visited another hospital before visiting our department.The diagnosis was not made even after cervical spine magnetic resonance imaging,electrodiagnostic study,brain magnetic resonance imaging,and arteriography were conducted.The patient performed unique exercises that stretched the pectoralis minor and coracobrachialis muscles.On the follow-up electrodiagnostic study,abnormal spontaneous activities in the bilateral biceps and brachialis muscles were observed.The patient was diagnosed with bilateral musculocutaneous neuropathy.Steroid pulse therapy was administered for approximately 6 wk.After treatment,his muscle strength returned to the predisease condition.CONCLUSION Clinicians should be aware of this condition,have adequate understanding of anatomy,and advise to correct inappropriate exercises.
