Imaging of Acute Bilateral Paramedian Thalamic and Mesencepahlic Infarcts AJNR 24:2005-2008, Matheus,M.G. &Castillo,M., 2003 See this aricle in Pubmed Article Abstract Thalami and midbrain arterial supply arises from many perforating blood vessels with a complex distribution for which many variations have been described. One rare variation, named the ôartery of Percheron,ö is a solitary arterial trunk that arises from one of the proximal segments of a posterior cerebral artery and supplies the paramedian thalami and the rostral midbrain bilaterally. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. We describe three patients with a presumed occlusion of the artery of Percheron in whom MR imaging showed characteristic symmetrical bilateral paramedian thalamic and mesencephalic infarctions.
