Infarction of the corpus callosum (CC) is rare because it receives a rich supply of blood from the anterior and posterior circulation.1 We present a patient with severe haemodynamic insufficiency (HI) of the cerebral hemisphere due to steno-occlusive disease of the bilateral internal carotid arteries (ICA). His ipsilateral hemisplenial infarction of the CC enlarged progressively. We discuss the clinical relevance of the splenium of the CC as a border-zone (BZ) area between the anterior- and posterior cerebral arteries (ACA, PCA).
Case report
This 63-year-old right-handed man with a medical history of hypertension and diabetes mellitus presented with dysarthria, lack of motivation and memory difficulties. MRI showed multiple acute infarcts in the internal BZ area and a single spotty infarct in the hemisplenium of the CC on the left side (figure 1A). We considered his dysarthria to be attributable to infarction of the BZ area, but we did not know whether the infarct in the CC hemispelnium was asymptomatic or played no role in his memory disturbance. Magnetic resonance- and digital subtraction angiography (MRA, DSA) revealed occlusion of the left ICA and severe stenosis of the right cervical ICA. The capacity of the left PCA was …
