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

Abstract

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.
