Thoracoabdominal radiculopathy.

Abstract

Thoracic nerve root dysfunction (TNRD) manifested as abdominal pain is an infrequently reported condition. We present data on six patients who had chronic intermittent thoracoabdominal pain originating in the back. Diabetes and osteoarthritis of the spine were the chief causes of these symptoms. The electromyogram in all patients showed changes consistent with an acute radiculopathy. All patients responded to anti-inflammatory therapy in combination with phenytoin, carbamazepine, amitriptyline, or local nerve block. TNRD is a condition that may be diagnosed earlier if clinical suspicion is increased, thus sparing patients excessive testing and surgery, and affording quicker relief.
