Sciatic nerve neurinoma is a rare disease and is often diagnosed as 'disk related disorder disease'. A case is reported of a patient with low back pain and sciatica who underwent surgery because of lumbar stenosis and spondilolisthesis. After surgery right side-sciatica remained. Further investigations (Ultrasonography, MRI) identified a neurinoma of the sciatic nerve. These diagnostic procedures were unable to clarify which nerve branch was involved (sciatic nerve, internal or external sciatic popliteal nerve). Neurophysiological studies are not usually included in the routine evaluation of Neurinoma. In our case nerve conduction studies showed a focal reduction of motor conduction velocity of the internal sciatic popliteal nerve in the tumor region. The surgical specimen confirmed the neurophysiological findings. These studies enabled the surgeon to evaluate the surgical criteria and the prognosis.
