Schwannomas are common, truly encapsulated and benign peripheral nerve sheath tumors. Their occurrence in extracranial locations is rare. Schwannomas most commonly occur in adults between 20 and 50 years of age. Their symptomatology usually mimics sciatic pain due to herniated disc. The most common clinical presentation of sciatic nerve schwannoma is a painful palpable mass. A 40-year-old woman was admitted to our neurosurgery department with a slow-growing mass at the medial right posterior thigh. Magnetic resonance imaging (MRI) showed a mass involving the right sciatic nerve in its middle portion. No neurological deficit was noted postoperatively. The result of the histopathological examination was reported as schwannoma. We report a case of large sciatic schwannoma with chronic sciatica.
施万细胞瘤是常见的、真正有包膜的良性周围神经鞘瘤。它们发生于颅外部位的情况较为罕见。施万细胞瘤最常发生于20至50岁的成年人。其症状通常类似于椎间盘突出引起的坐骨神经痛。坐骨神经施万细胞瘤最常见的临床表现是可触及的疼痛性肿块。一名40岁女性因右大腿后内侧缓慢生长的肿块入住我院神经外科。磁共振成像（MRI）显示肿块累及右侧坐骨神经中部。术后未发现神经功能缺损。组织病理学检查结果报告为施万细胞瘤。我们报告一例伴有慢性坐骨神经痛的巨大坐骨神经施万细胞瘤病例。
