Seventeen patients (age 23-81) having the "top of the basilar" syndrome were the subjects of this study. They were evaluated clinico-radiologically. The diagnosis of this syndrome was made by computerized tomography. The infarcted lesions of each patient were widely distributed in many areas among the thalamus, midbrain, pons, cerebellum, and occipital lobe. Both the thalami were involved in 8 patients. When the thalamus was involved bilaterally, the low density areas of both the thalami were demonstrated to be almost the same in size and symmetric in localization by computerized tomography, showing a characteristic pattern. Further, magnetic resonance imaging could reveal small lesions in the brain stem minutely. Angiography revealed that stenosis or occlusion was within the circle of 2 cm in diameter surrounding the five-forked road of the top of the basilar artery in 84.6%. Recanalization of the occluded artery occurred in 61.5%, which suggests that the embolism plays an important role in appearance of this syndrome. In spite of frequent recanalization hemorrhagic infarction never occurred. The prognosis was very poor.
