Arteriogenic Thoracic Outlet Syndrome Presenting as Cervical Radiculopathy

Thoracic outlet syndrome (TOS) is an infrequent entity encountered by medical practitioners attributed to compression of the neurovascular structures passing through the thoracic outlet. Here, we report the presentation of a young adult who was referred for workup of cervical radiculopathy and was planned to undergo an anterior cervical discectomy and fusion. A dynamic cerebral angiogram was performed and confirmed the diagnosis of arteriogenic TOS. The etiology, presentation, and diagnostic workup of TOS are briefly discussed with emphasis placed on maintaining a healthy suspicion in order to differentiate from cervical radiculopathy, make an accurate diagnosis, and avoid inappropriate surgery.
