Abstract

MR neurography Schwannoma Tinel sign
Other causes such as peripheral schwannomas can mimic lumbar disk disease. We present an unusual case of multiple nerve sheath tumors in a patient with left radicular leg pain accompanied by a Tinel sign. Initial lumbar MR imaging revealed a mass in the right lumbar plexus, side opposite the patient's symptoms. Magnetic resonance neurography subsequently revealed a compressive mass of the sciatic nerve proximal to the popliteal fossa, histologically identified as a schwannoma. This case emphasizes the importance of continued investigation when the radiographic findings do not correlate with the patient's history in the presence of localizing signs on physical examination.
