Klüver–Bucy syndrome secondary to a nondominant middle cerebral artery ischemic stroke: a case report and review of the literature

BACKGROUND: Klüver–Bucy syndrome is a rare and complex neurobehavioral cluster that occurs in humans and results from a temporal lobe lesion. It can be associated with a variety of causes. Stroke is a rarely reported cause of this syndrome. CASE PRESENTATION: In this report, we present the case of a 68-year-old Saudi male who developed Klüver–Bucy syndrome subsequent to a nondominant middle cerebral artery ischemic stroke involving right temporal lobe. The patient manifested most of the Klüver–Bucy syndrome clinical features, including hypersexuality, hyperphagia, hyperorality, and visual hypermetamorphosis (excessive tendency to react to every visual stimulation with a tendency to touch every such stimulus). These neurobehavioral manifestations improved after he was started on treatment. CONCLUSIONS: The clinical course, anatomical association relying on pathophysiology, and potential treatment have all been deliberated in regard to the rare occurrence of Klüver–Bucy syndrome resulting from temporal lobe pathology.
