To present the imaging findings for two cases of intramedullary schwannoma involving the thoracic cord and the conus medullaris.
a 34-year-old man and a 53-year-old woman presented with symptoms of weakness and pain in the lower limbs. Myelography and magnetic resonance imaging as well as other examinations, were performed.
The imaging failed to indicate the correct diagnosis in either patient. However, intramedullary schwannoma was confirmed pathologically in both patients. Subtotal excision resulted in local tumour recurrence at 5 and 3 years, respectively.
Intramedullary schwannoma should be considered in the differential diagnosis of spinal cord tumours. The importance of accurate diagnosis from frozen sections at surgical biopsy is emphasized .
介绍两例累及胸段脊髓和圆锥的髓内神经鞘瘤的影像学表现。
一名34岁男性和一名53岁女性表现为下肢无力和疼痛症状。进行了脊髓造影、磁共振成像及其他检查。
影像学检查均未能在两名患者中明确正确诊断。然而，两名患者经病理证实均为髓内神经鞘瘤。次全切除分别在5年和3年后导致局部肿瘤复发。
在脊髓肿瘤的鉴别诊断中应考虑髓内神经鞘瘤。强调了手术活检时从冰冻切片进行准确诊断的重要性。
