OBJECTIVES

The purpose of this study was to clarify etiologic factors, prior symptoms and clinical features of isole superior cerebellar artery (SCA) territory infarcts.

METHODS

All data were collected from consecutive 21 patients with isole SCA infarcts involved on computerized tomography.

RESULTS

The risk factors including hypertension, cardiopathy and rhythm disturbances, hyperlipidemia, diabetes mellitus, abnormality in homeostasis, smoking, oral contraceptive have been identified. Headache, nausea-vomiting, vertigo, gait imbalance and diplopia were the most common complaints at onset.
