Malignant schwannoma of brachial plexus presenting as spinal cord compression.

A 40-year-old male presented clinically with features of C6 radiculomyelopathy. An intradural extramedullary malignant schwannoma was removed at laminectomy. Foraminal extension of the tumour could not be removed in spite of foraminotomy, and no root attachment was found. Frequent intraspinal recurrences were treated with local resection. Delayed appearance of a supraclavicular mass, CT scan and exploration of supraclavicular fossa disclosed its origin from the upper trunk of brachial plexus.
