Artery of Percheron Occlusion: A Rare Unusual Cause of Acute Bithalamic and Mesencephalic Stroke – A Case Report
Journal Title: Scholars Journal of Medical Case Reports - Year 2016, Vol 4, Issue 5
Abstract
Arterial supply of thalami and midbrain originates from many perforating vessels with a complex distribution for which many variations have been described. Artery of Percheron is one such variation in which a single arterial trunk arises from proximal segment (P1) of one of the posterior cerebral artery (PCA) and supplies bilateral paramedian thalami and rostral midbrain. Occlusion of this artery, although uncommon results in characteristics pattern of symmetric infarction in bilateral medial thalami with or without mesencephalic infarction. We here describe clinical and MR imaging findings in presumed occlusion of artery of Percheron with typical relatively symmetric infarctions in bilateral paramedian thalami and rostral midbrain. Keywords: Percheron, Thalami, Midbrain, Infarction, MRI, DWI.
