Bilateral thalamic infarction due to artery of Percheron occlusion: a case report Authors Maleeha Shah Department of Medicine, MTI Khyber Teaching Hospital, Peshawar, Pakistan Muhammad Daniyal Nadeem Department of Medicine, MTI Khyber Teaching Hospital, Peshawar, Pakistan Ayesha Saleem Department of Surgery, MTI Hayatabad Medical Complex, Peshawar, Pakistan Muhammad Taimoor Khan Department of Clinical Vascular Neurology, The National Institute of Health, Islamabad, Pakistan Neelam Asghar Allama Iqbal Medical College, Lahore, Pakistan DOI: https://doi.org/10.47391/JPMA.1664 Abstract The artery of Percheron is a rare variant of the posterior cerebral circulation. It is characterised by a single arterial trunk that supplies blood to bilateral paramedian thalami and rostral midbrain. Its occlusion can have a very wide range of presentation, and initial imaging including CT of the head maybe normal. Diagnosis and eventual treatment is usually delayed. We describe the case of an elderly man who presented with loss of consciousness, aphasia, and bilateral lower limb weakness. He was diagnosed with bilateral thalamic infarction due to the occlusion of the artery of Percheron only after an MRI of the brain was performed. Despite treatment his symptoms did not resolve completely. Keywords: Thalamus/blood supply, Cerebral arteries, Magnetic Resonance Imaging. Published 2022-01-05 How to Cite Shah, M., Nadeem, M.
