摘要
目的:研究基底动脉尖综合征(Top of the Basilar Syndrome,TOBS)的临床和影像学表现,加深对这种疾病的认识。方法:对30例TOBS患者的临床症状和体征进行分析,并行头颅CT及MRI检查明确病变的部位。结果:8例经头颅CT确诊,余22例经MRI确诊。CT及MRI提示重要的特征是中脑或丘脑梗塞合并其他部位梗死,如枕叶、小脑、颞叶。结论:TOBS的诊断主要依赖临床及影像学表现,MRI对后颅凹病变诊断优于CT。
Objective:To study the clinical manifestation, characteristics of Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) on patients with Top of the Basilar Syndrome (TOBS). Methods:Symptoms and physical signs of 30 patients with TOBS were analyzed ,and CT and MRI were performed to clarify the locations of lesions. Results:Of all the 30 patients,8 cases were diagnosed by CT and the others were diagnosed by MRI. CT and MRI showed that the most important feature of TOBS was infarction in both sides of thalamencephalon or midbrain accompanied by infarctions in cerebellum, occipital and temporal lobes. Conclusions:The diagnosis of TOBS mainly depended on the clinical manifestation and imaging tests. MRI was better than CT scan in detecting lesions in posterior fossa .
