成人桥脑延髓腹侧肠源性囊肿(附六例报告)

目的 探讨成人桥脑延髓腹侧肠源性囊肿的临床特征,以提高对该疾病认识.方法 对2000年7月至2007年2月经手术治疗且病理证实的桥脑延髓腹侧肠源性囊肿6例患者进行回顾性研究.结果 男4例,女2例,平均发病年龄30.5岁.以头颈部疼痛、头晕作为首发症状,MRI表现多样.采用远外侧入路或乙状窦后入路病变切除术,1例全切除,5例近全切除,4例术后出现短暂性发热.平均随访49.3个月,未见复发.结论 桥脑延髓腹侧肠源性囊肿多见于青壮年,临床表现以头痛、头晕为主,影像学变化多样,误诊率高.手术切除是最佳治疗选择,不必勉强切除与桥脑延髓腹侧紧密粘连的囊壁,本病患者预后良好.

Clinical study on enterogenous cysts ventrally to pons-medulla in adults

Objective To investigate the clinical characteristics of enterogenous cysts ventrally to ports - medulla in adults. Method Six cases of ventrical brain stem enterogenous cyst were operated in our hospital between Jul. 2000 and Feb. 2007. The clinical characteristics and outcome of them were reviewed. Results There were 4 male and 2 female patients. The mean age of presentation was 30. 5 years. Head and dizziness were the first clinical symptom. The preoperative imagings varied according to each patient. All 6 lesions were resected by far - lateral or retrosignoid approach, and one lesion was totally removed, the other 5 were subtotally resected. 4 patients suffered from transient febrile after operations. All patients were followed - up for long - last, and none of them presented signs of recurrence. Conclusions Enterogenouscysts ventrally to pons- medulla are rare lesions occuring in young adults. Symptoms of head and dizziness are the mainly clinical presentation. Misdiagnosis is more frequent for the complicated neuroimagings. Resection is the best treatment for the lesion, but it is undeserved for radical resection in the risk of demolishing brainstem. This lesion has a favorable prognosis.
