ABSTRACT
We report a rare case of multiple hereditary exostosis where patient presented with bilateral base of neck exostoses with concurrent compression of brachial plexus and subclavian artery and vein. The patient was a young 26-year-old woman with chief complaints of pain in the left upper extremity, paresthesia in the left ring and little finger, and weakness in hand movement and grip. On referral, history, physical examination, radiological imaging, and electrodiagnostic tests evaluated the patient. Due to severe pain and disability in performing routine activities, surgical intervention was necessary. In the current case, the patient had thoracic outlet syndrome with concomitant venous, arterial, and neurogenic sub types. Radial pulse returned and pain associated with brachial plexus compression was resolved after the surgery.
