MiraDry^®, a microwave thermolysis device, is comparably new non-surgical agent in the field of eradication of sweat glands for treating axillary hyperhidrosis and osmidrosis. So far, altered sensation, swelling, and compensatory sweating are widely known as adverse effects of MiraDry^®. Of the few reported MiraDry^®-induced neuropathy cases, median and ulnar neuropathies are common. Although, one case has described radial nerve and posterior cord damage with maximized stimulation intensity, musculocutaneous nerve damage induced by MiraDry^® has not been reported. Here, we report a case of a 30-year-old woman experiencing left hand weakness after receiving MiraDry^® at a local dermatology clinic. Left brachial plexopathy, mainly involving the median nerve and the musculocutaneous nerve with partial axonotmesis, was confirmed by electrodiagnostic studies. Ultrasound evaluation showed corresponding results. This is the first case report of the musculocutaneous neuropathy by MiraDry^®.
