A Heart Sign in Medial Medullary Infarction

INTRODUCTION: Bilateral medial medullary infarction (MMI) is a rare stroke syndrome. MMI presents acutely or subacutely, presenting with dysarthria, dysphagia, quadriparesis, quadriplegia and sometimes complicated by respiratory disorder, resulting in poor prognosis. Diagnosis of bilateral MMI was initially difficult on brain MRI but with advent of newer sequences like DWI (diffusion weighted images) its been fairly possible. We report the case of a patient who was diagnosed with bilateral MMI based on MRI features of classical “heart shaped” sign.
