A n Autopsy Case of Cerebellar Hemorrhagic Infarction in the Region of the Bilateral Superior Cerebellar ArteriesT etsumori

The authors describe an autopsy case of cerebellar hemorrhagic infarction in the region of the bilateral superior cerebellar arteries (SCA). A 79-year-old woman suddenly developed dysarthria, bilateral blepharoptosis, external ophthalmoplegia, left hemiparesis, dysphagia and dysuria. CT scan revealed low density in the bilateral cerebellar hemispheres. Angiography revealed narrowing of the distal portion of the basilar artery. The patient made a gradual recovery in the first two weeks, but she died of a hyperglycemic non-ketotic diabetic coma on the 32nd day. Autopsy disclosed recent hemorrhagic infarctions of the bilateral SCA regions and of right Ammon's horn and numerous softenings of the brain stem, together with an old cystic infarction in the region of the middle cerebral artery. There were no occlusions in either the basilar or superior cerebellar arteries. It was suggested that an embolization due to severe athero sclerosis of the distal portion of basilar artery affected its pontine branches and bilateral SCA.
