多发神经鞘瘤

目的 探讨多发神经鞘瘤的临床特点和治疗方法。方法 对１９７５年１月～１９９９年１２月收治的９例多发神经鞘瘤进行回顾性分析。结果 ９例中有７例术前发现肿瘤数目少于术中所见。９例均行手术治疗，其中５例行剥除术，４例行神经切除术，术后４例复发。结论 多发神经鞘瘤术前检查不易明确肿瘤数目，充分的朴前检查包括ＭＲＩ是必要的。对重要神经上的多发神经鞘瘤应行剥除术。该病术后容易局部复发。

Multiple schwannomas

Objective To study the clinical features and treatment of multiple schwannomas (neurilemmomas). Methods 9 patients with multiple schwannomas treated with surgery from 1975 to 1999 were reviewed retrospectively. Results In 7 of the 9 cases of schwannomas, the number of tumor lesions was seen more than that diagnosed preoperatively. All the patients had surgical resection; 5 had enucleation and 4 had tumors excised with the invovled nerve. Recurrence occured in 4 patients. Conclusion Because of the difficulty in predetermination of the exact lesional number, thoroughly preoperative examination including MRI is nessesary. Enucleation is recommended to those tumors involving important nerves. There is a high rate of recurrence.
