Intradural lumbar cystic schwannomas are a very rare entity and only 10 case reports have been reported in the literature. The diagnosis and management remains a challenge for clinical physicians. Herein, we report a 51-year-old female presenting with lower back pain and radiating pain at the left upper thigh. Magnetic resonance images of lumbar spine demonstrated an intradural cystic mass approximately 18 x 17 x 35 mm in size occupying L4 to L5, which appeared as the same signal intensity as CSF. At operation, a well encapsulated cystic mass was found. The pathological examination confirmed a diagnosis of schwannoma. The relevant literature was also reviewed.
硬脊膜内腰椎囊性神经鞘瘤是一种非常罕见的疾病，文献中仅报道过10例病例报告。其诊断和治疗对临床医生来说仍然是一项挑战。在此，我们报告一名51岁女性，表现为下背部疼痛和左大腿前侧放射性疼痛。腰椎磁共振成像显示一个大小约为18×17×35mm的硬脊膜内囊性肿块，占据L4至L5节段，其信号强度与脑脊液相同。手术中发现一个包膜完整的囊性肿块。病理检查确诊为神经鞘瘤。我们还对相关文献进行了回顾。
