Objective For understanding its clinical features and pathogenesis, six cases of Top ofthe Basilar syndrome (TOB-syndrome) were reported. Method The imaging results ofTOB-syndrome were analysed using CT scan and MR Imaging of six cases. Results CT scanand MR Imaging showed that the most important pathological features of TOB-syndrome issymmetrical papilionaceous infarction in bithalamus, whose pathogenesis is disturbance ofblood circulation at the crossing site of the right and left posterior cerebral arteries, and theright and left superior cerebellar arteries, and at the top end of the basilar artery within 2cmin diarnetes. The clinical rnanifestion is the sudden unconsciousness with the dilation of thepupils and the dismovement of the eyeballs as well as the behavior disorder. ConclusionTOB-syndrome often manifested infarction of bithalamus’ brainstem’ cerebellum. Theprognosis of the syndrome is poor, complete recovery is not common.
