脑干肿瘤早期征象不典型。CT极易漏诊,脑室碘油及气脑造影定性困难。腰穿检测脑脊液压力及蛋白定量、白细胞计数早期大部正常,常误为脑干脑炎、脱髓鞘疾病、共济失调。椎基底动脉供血不足等疾病。MRI对诊断与鉴别诊断有帮助。本文综合117例脑干肿瘤的CT、MRI、脑室造影及临床资料,分析误诊因素,探讨诊断与鉴别诊断要点.
Early signs of brain stem tumors are not typical. CT easily missed diagnosis, intraventricular lipiodol and angiography qualitative difficulties. Lumbar puncture detection of cerebrospinal fluid pressure and protein quantification, most of the early white blood cell count normal, often mistaken for encephalitis, demyelinating disease, ataxia. Vertebrobasilar insufficiency and other diseases. MRI diagnosis and differential diagnosis helpful. In this paper, 117 cases of brain stem tumors CT, MRI, ventricular angiography and clinical data to analyze the misdiagnosis factors to explore the diagnosis and differential diagnosis.
