Recurrent artery of Heubner (RAH) arising from what artery?
Recurrent artery of Heubner (RAH) is the largest perforating branch of the proximal anterior cerebral artery (ACA), arising from the proximal A2 in 90% of cases, and from the distal A1 in 10% of cases.
Examination demonstrates an acute stroke with prominent diffusion signal abnormality and matching diffusion restriction, affecting the right recurrent artery of Heubner involving the head of the right caudate nucleus, right anterior cerebral artery pericallosal branch along the right cingulate gyrus and medial right frontal cortex, right middle cerebral artery superior division involving supra Sylvian lateral frontal and parietal cortex, infarction involving the splenium of the corpus callosum to the left of midline, infarct involving the medial left temporal lobe hippocampal and parahippocampal hippocampal gyri.
