title: [A Case of Schwannoma Originating from the Sciatic Nerve].
abstract: A 75-year-old man was admitted with abdominal pain and taken to our hospital. CT and MRI showed a tumor measuring 60mm in diameter in the pelvic cavity. Based on the imaging findings, we suspected a schwannoma and decided to perform surgery. As the tumor was found to be benign in intraoperative frozen section diagnosis, the tumor was enucleated. Histopathological findings showed no nuclear atypia, and the patient was diagnosed with a schwannoma. He complained of paresthesia in his right leg after surgery, and underwent walking training. Six months after surgery, no recurrence was found.
