Cartilage-containing meningiomas are extremely uncommon, and such tumors located in the spinal cord of a child have not previously been reported. We describe a case of cartilaginous spinal meningioma in a 13-year-old girl. The tumor lacked typical histopathological features of meningioma on light microscopic examination, and the final diagnosis was possible only after an extensive study by electron microscopic examination. The case is evaluated with a focus on differential diagnosis and review of the literature.
含软骨的脑膜瘤极为罕见,此前尚无位于儿童脊髓的此类肿瘤的报道。我们描述了一名13岁女孩的软骨性脊髓脑膜瘤病例。该肿瘤在光镜检查下缺乏脑膜瘤典型的组织病理学特征,仅在经过广泛的电镜检查研究后才得以最终确诊。本文对该病例进行了评估,重点在于鉴别诊断并对文献进行综述。
