As the corpus callosum receives a rich blood supply from both anterior and posterior circulation, corpus callosum infarction is a rare diagnosis. The often complex clinical presentation, which also lacks specificity, can be attributed to the inherent complexity of physiologic function conducted by the corpus callosum. The most common initial presentation in these patients includes higher-level neurological dysfunction such as cognitive impairment, mental disorder, and sleep disorder with or without mild-to-moderate sensory and motor deficits. Given this wide spectrum of presentations, delayed diagnosis or treatment of these patients is common, which may contribute to the poor prognosis and higher recurrence rates associated with this diagnosis.
