Intramedullary schwannomas are rare spinal cord tumors. Most of these tumors have been reported as a single lesion in the spinal cord. Up until today approximately 50 cases of intramedullary shwannomas not related to neurofibromatosis have been described. We describe a rare case of thoracic intramedullary tumour in a 28 year old male patient who presented with progressive weakness of both the lower limbs and decreased sensation below D2 dermatomal level. Magnetic resonance imaging revealed an intramedullary lesion from D1 toD7. D1 to D7 laminoplasty and near total excision of the mass done. Total removal was difficult because of the infiltrative nature of the tumour. Histopathological report confirmed the diagnosis of the schwannoma. Possible site of origin and pathogenesis of intramedullary tumour have been discussed.
髓内神经鞘瘤是罕见的脊髓肿瘤。这些肿瘤大多被报道为脊髓中的单个病灶。截至目前，已描述了约50例与神经纤维瘤病无关的髓内神经鞘瘤病例。我们描述了一例罕见的胸段髓内肿瘤病例，患者为一名28岁男性，表现为双下肢进行性无力以及D2皮节水平以下感觉减退。磁共振成像显示从D1至D7有一个髓内病变。进行了D1至D7椎板成形术并近乎完全切除肿块。由于肿瘤的浸润性，完全切除很困难。组织病理学报告证实了神经鞘瘤的诊断。文中讨论了髓内肿瘤可能的起源部位和发病机制。
