THE SYNDROME OF THROMBOSIS OF THE POSTERIOR INFERIOR CEREBELLAR ARTERY: A REPORT OF 28 CASES

Abstract
The findings in 28 cases of thrombosis of the posterior inferior cerebellar artery are presented, with an analysis of the symptoms and neurologic abnormalities. In most cases there was a sudden onset of vertigo, falling, unilateral ataxia, vomiting, diplopia, paresthesias, dysphagia and dysphonia. Homer''s syndrome, cerebellar signs, unilateral palatal paralysis, ipsilateral loss of pain and temp. perception of the face and contralateral loss of the trunk and extremities were observed. Late follow-up examination in 10 cases revealed a persistence of certain abnormalities. Although most cases presented all or most of the typical signs and symptoms, it is emphasized that there was much variation in the clinical picture, due to differences in their relative severity.
