Schwannoma, Sciatic nerve, Peripheral nerve tumor

Schwannoma, a benign tumor of the peripheral nerve

sheath, though not very uncommon but its location in

the sciatic nerve is relatively rare. Patients generally

present with radiculopathy type pain radiating to the

leg. These patients need exclusion of other common

entities on clinical and radiological examination, before

considering a differential diagnosis of sciatic nerve

schwannoma. These patients generally lack complaint

of low backache and has normal appearing lumbar

spine on MRI. Since the lesion in the index case was

located in the popliteal fossa, Becker’s cyst needed

exclusion. We report a rare case of sciatic nerve

schwannoma in a 40-year-old female who presented

with pain and soft tissue swelling in popliteal fossa of

long duration and discuss the preoperative

management. The patient underwent uneventful

surgical resection along with preservation of lower limb

motor and sensory function.
