Schwannoma of the brachial plexus

Brachial plexus schwannomas are rare formations that make up only about 5% of all schwannomas. Given the complex anatomical features of tumor localization, they may represent an extraordinary problem for a surgeon. A 36-year-old patient with clinical signs of left brachial plexus neoplasm is presented. After the diagnosis, a total tumor removal was performed using neurophysiological monitoring and preserving unaffected nerve fibers via supraclavicular surgical access with oblique clavicle osteotomy. After the operation, there was a decrease in sensitivity in the left shoulder area and an increase of left shoulder abduction and flexion paresis with subsequent restoration of motor function at the 5th day after the operation. Despite its benign nature, brachial plexus schwannomas require surgical treatment. Careful preoperative planning of surgical access is a prerequisite for a favorable outcome. With the use of neurophysiological monitoring, it is possible to achieve total tumor removal without permanent neurological impairment.
