Acute bilateral cerebellar infarction in the territory of the medial branches of posterior inferior cerebellar arteries

Clin Neurol Neurosurg. 2001 Oct;103(3):194-6. doi: 10.1016/s0303-8467(01)00139-1.


The most frequent type of cerebellar infarcts involved the posterior inferior cerebellar artery (PICA) and superior cerebellar artery territories but bilateral involvement of lateral or medial branches of PICA is extremely rare. In this report, we present a 55-year-old male who admitted to hospital with vomiting, nausea and dizziness. On examination left-sided hemiparesia and ataxic gait were detected. Infarct on bilateral medial branch of PICA artery territories was found out with cranial magnetic resonance imaging (MRI) technique and 99% stenosis of the left vertebral artery was found out with digital subtraction arteriography. The patient was put on heparin treatment. After 3 weeks, his complaints and symptoms had disappeared except for mild gait ataxia.
