椎管内毛细血管瘤合并黏液乳头室管膜瘤的临床特点(附1例报告)

Clinical characteristics of capillary hemangioma combined mucus nipples ependymoma in spinal canal( report of 1 case)

目的探讨椎管内毛细血管瘤合并黏液乳头室管膜瘤的临床特点。方法对1例椎管内毛细血管瘤合并黏液乳头室管膜瘤患者的临床资料进行回顾性分析。结果本例患者为中年男性,缓慢起病,主要表现右下肢麻木、痛觉减退,腰椎MRI示L2椎体水平椎管内马尾丛内1个小类圆形及L5椎体水平椎管内1个分叶状长T1、长T2信号影,推挤周围终丝﹑马尾神经;增强扫描2个病灶均有明显均匀的强化。给予手术完整切除椎管内2个肿瘤。病理诊断示肿瘤1(L5水平)为毛细血管瘤,肿瘤2(L2水平)为黏液乳头型室管膜瘤(WHOⅠ级)。术后患者的症状明显缓解。结论椎管内毛细血管瘤合并黏液乳头室管膜瘤的症状缺乏特异性;MRI可明确其部位、形状,应及时行肿瘤切除术并予病理检查确诊。

Objective To investigate the clinical characteristics of capillary hemangioma combined mucus nipples ependymoma in spinal canal.Methods The clinical data of one patient with capillary hemangioma combined mucus nipple ependymoma in spinal canal was retrospectively analyzed.Results The patient was a middle-aged man,with the onset slowly and the clinical symptoms were the right lower extremity numbness and pain subsided.The MRI respectively showed a round-like obsject located on the level of L2 vertebral level plexus and a small lobulated obsject on the level of L5 and showed long T1 and long T2 signal,which pushing spinal final wire and cauda equina.The enhanced scan showed that both of the two lesions were significantly homogeneous enhancement.The two spinal tumors were received completed surgical resection.The pathological diagnosis showed that one tumor was capillary hemangioma （L5 level） and the other （L2 level） was mucus nipples ependymoma （WHO I grade）.The symptoms of the patient relieved obviously after operation.Conclusions The patient with capillary hemangioma combined mucus nipple ependymoma in spinal canal is lack of specific symptoms.MRI can clarify its position and shape.Surgical removal of the tumor should be timely treated.The pathological examination can make a definite diagnosis.
