The authors report a rare case of primary spinal ependymomatosis in a young adult man. Multiple primary ependymomatous lesions were seen on magnetic resonance imaging and no anaplasia was identified on the surgical-pathological analysis. The aetio-pathological mechanism and surgical significance of this rare occurrence is discussed.
A 26-year-old man of Polish origin presented with a ten-day history of pain in the left leg and lower back. This was followed by difficulty in urinating and a decrease in sensation in both legs. Examination revealed pyramidal signs and mild weakness in both lower limbs. He had early sphincter involvement requiring catheterization. Magnetic resonance imaging of the brain was normal. However, that of the spinal cord revealed multiple intradural spinal lesions, both intra- and extramedullary, extending from the cervical cord down to the cauda equina roots. T12-L1 laminectomy was performed. Multiple intradural, extra- and intra-medullary tumors were seen. After the operation, the patient deteriorated with a sensory level at T4. Post-operative cranio-spinal radiotherapy was administered but there was no clinical improvement in the lower limbs.
Primary spinal ependymomatosis is a rare phenomenon involving multiple spinal segments in the absence of a primary intracranial tumor. Radical excision is unrealistic in this condition. Biopsy followed by radiotherapy is the preferred method of treatment.
作者报告了一例年轻成年男性原发性脊髓室管膜瘤病的罕见病例。磁共振成像显示多个原发性室管膜瘤病变,手术病理分析未发现间变。讨论了这种罕见情况的病因病理机制和手术意义。
一名26岁的波兰裔男子,左腿和下背部疼痛10天。随后出现排尿困难和双腿感觉减退。检查发现双侧下肢有锥体束征和轻度无力。他早期出现括约肌受累,需要导尿。脑部磁共振成像正常。然而,脊髓磁共振成像显示多个硬脊膜内脊髓病变,包括髓内和髓外,从颈髓延伸至马尾神经根。进行了T12-L1椎板切除术。可见多个硬脊膜内、髓外和髓内肿瘤。术后,患者病情恶化,感觉平面在T4。术后进行了全脑脊髓放疗,但下肢无临床改善。
原发性脊髓室管膜瘤病是一种罕见现象,在无原发性颅内肿瘤的情况下累及多个脊髓节段。在这种情况下,根治性切除是不现实的。活检后放疗是首选的治疗方法。
