Abstract
Introduction: Cerebellar infarcts usually occur in the territory of the posterior inferior cerebellar artery (PICA) and tend to be unilateral. Simultaneous bilateral involvement is extremely rare.
Case report: We present the case of a 67-year-old male who developed an acute cerebellar syndrome secondary to acute infarction in the territory of both PICA confirmed by nuclear magnetic resonance imaging. Non-valvular paroxysmal atrial fibri- llation was the most plausible etiology after digital cerebral angiography ruled out vascular abnormalities. Conclusion: This case shows that bilateral infarction in the territory of both PICA can occur in the context of cardiac embo- lism, even in the absence of an anomalous common PICA.
