Thoracic Outlet Compression Syndrome Caused by a Schwannoma of the C7 Nerve RootFrom the Department of Surgery, University of Louisville, Louisville, Kentucky, USA Correspondence: Dr E. Atasoy, Christine M. Kleinert Institute for Hand and Micro Surgery, Suite 850, 225 Abraham Flexner Way, Louisville, Kentucky 40202 3840, USA. This is the first report of a schwannoma originating from the C7 nerve root causing thoracic outlet compression syndrome. The patient was a 30-year-old woman with a 3-year history of numbness on the radial side of the left hand, left arm tiredness, nocturnal pain in the left forearm and pain in the left elbow, shoulder and neck. Conservative treatment and previous operations, including carpal tunnel release and first rib resection, provided no relief. A left scalenectomy was performed. During the removal of the anterior scalene muscle, a mass approximately 3 cm long and 1.5 cm in diameter was noted under the anterior scalene muscle involving the C7 nerve root. The tumour was encapsulated and covered with attenuated and stretched nerve fascicles. It was completely excised without disturbing the nerve fascicles. The clinical impression was schwannoma, which was confirmed on pathological examination.
