| Description | We present a rare case of corpus callosum ischemia (CC). The CC is the largest white matter structure of the brain and is the main commissural pathway connecting the two cerebral hemispheres, consisting of 200-250 million contralateral axonal processes. The blood supply to the CC is provided mainly from the carotid basin (mainly via the arteria cerebri anterior [ACA] and additionally from the arteria communicans anterior [ACoA]), and partly from the vertebrobasilar basin. The rostrum and genu are supplied by the subclavian and medial callosal arteries arising from the ACoA. Four branches arise from the pericallosal artery (a continuation of the ACA) and provide most of the supply to the body of the CC. The posterior pericallosal artery, a branch of the arteria cerebri posterior (ACP), is a short penetrating arteriole supplying the splenium. There are anastomoses between the callosal branches of the ACA and ACP near the tip of the splenium. Thus, an isolated occlusion supplying branches from the ACA or ACP watershed does not necessarily lead to interruption of blood supply and subsequent infarction. Given this, CC ischemias are relatively rare. |
