Restricted diffusion and T2 hyperintensity in the right anterior cerebral artery territory. Occluded right pericallosal artery best demonstrated on VR.
Pericallosal artery infarctions are a rare localization of stroke, mostly occurring as partial infarctions due to distal anterior cerebral artery pathology. Clinically, they are mainly characterized by hemiparesis predominately in the lower limb caused by involvement of supplementary motor cortex areas without affecting the corticospinal tract.
