Abstract |
Various complications of breast cancer surgery and axillary dissection have been reported, of which arm pain and sensory abnormality was reported mainly due to intercostobrachial nerve injury. We have experienced a rare case of medial forearm pain and numbness due to medial antebrachial cutaneous nerve (MACN) injury after axillary dissection. A 49-year old woman was consulted to department of physical medicine and rehabilitation for pain and numbness at medial side of left forearm after wide local excision of left breast cancer and axillary lymph node dissection. Sensory examination showed paresthesia and hypesthesia of left medial forearm although manual muscle test of left upper extremity was relatively normal. On sensory nerve conduction studies, the amplitude of left MACN decreased to 30% of right side. The motor nerve conduction studies and needle electromyography showed no abnormal findings. The patient was diagnosed with left MACN injury, and treated with medication and physical therapy. |
