Computed tomography of cerebral infarction along the distribution of the basal perforating arteries. Part II: Thalamic arterial group

Computed tomographic (CT) manifestations of cerebral infarction along the distribution of the basal perforating arteries were reviewed and correlated with cerebral angiography. Infarcts in the territories of perforators were demonstrated individually based on knowledge of their three-dimensional distribution as shown by microangiography of cadavers. In Part II of the study, the posterior areas supplied by the thalamic arteries were examined. Infarcts in the area supplied by the thalamotuberal arteries involved the anterior pole of the thalamus; those in the area of the thalamoperforate arteries involved the medial portion of the thalamus, along the lateral wall of the third ventricle; those in the area of the thalamogeniculate arteries involved the posterolateral portion of the thalamus; and those in the area of the choroidal arteries of the lateral ventricle involved the most posterolateral and dorsolateral portions of the thalamus. Clinical and neuroradiological correlations are discussed.
