Contralateral Hyperhidrosis After Large Acute Left MCA Territory Infarction: A Case Report

Abstract

A 51-year-old female presented with sudden onset of right-sided hemiparesis and aphasia. Imaging confirmed a left middle cerebral artery (MCA) territory infarct affecting the insular cortex. During her recovery, she developed excessive sweating exclusively on the right side of her body, leading to a diagnosis of contralateral hyperhidrosis. This case highlights the unusual presentation of hyperhidrosis following an MCA stroke and underscores the role of the insular cortex in autonomic regulation.
