Abstract:

Schwannoma are benign peripheral nerve tumors derived from the Schwann cells in the neural sheath. Sciatic nerve schwannoma in the lower extremity is uncommon, accounting for only 1% of all schwannoma cases. This report aimed to describe the functional recovery after lower limb surgery of sciatic nerve schwannoma with peripheral nerve block and without intraoperative neurophysiological monitoring (IOM) performed in Semen Padang Hospital in 2019. A 78-year-old woman presented with a complaint of pain on her slowly growing mass at the right popliteal region, which had existed for 22 years. Microsurgical resection was performed with local peripheral nerve block and without intraoperative neurophysiological monitoring. Tumor was removed en-bloc by sharp dissection using a microscope without any complication. The patient had significant pain relief without any neurologic deficit three weeks after the surgery.
