Splenium of corpus callosum acute infarction: posterior pericallosal artery territory

Case contributed by Dr Chris O'Donnell


Confusion, disorientation, right sided visual disturbance occurring 3 days post elective arthroscopy

Patient Data

Age: 55
Gender: Male

Restricted diffusion (confirmed on ADC) indicative of acute infaction producing cytotoxic edema involving the left splenium of the corpus callosum as well as the adjacent peritrigonal white matter and medial left temporal lobe.  High grade stenosis or occlusion of the left posterior cerebral artery

Case Discussion

Corpus callosum is richly vascularized thus not commonly infarcted.  The posterior pericallosal (or splenial) artery supplies the splenium.  It is a branch of the ipsilateral posterior cerebral artery (P3).  In this case the patient is presumed to have thrown off an embolus to the posterior cerebral artery and occluded the posterior pericallosal branch
