抄録

We have studied seven patients with infarction in the territory of the anterior choroidal artery.<BR>In all patients examination on admission revealed hemiplegia, hemianesthesia and homonymous hemianopsia, which were called the triad of infarction in the perfused area of the anterior choroidal artery. In addition to these signs, patients showed absence of spontaneous activity, disturbance of memory, and higher cortical signs, such as hemispatial agnosia and anosognosis. These signs were, however, transient and resolved within the acute stage. CT scan demonstrated an area of reduced denisty in the posterior limb of the internal capsule and the lateral geniculate body, sparing the thalamus, which corresponded exactly with the area of supply of the anterior choroidal artery. In some patients a cerebral angiogram revealed a stenosis at the origin of the anterior choroidal artery and irregularity on the wall.<BR>It may be possible to make a correct diagnosis on infarctio in the territory of the anterior choroidal artery with clinical signs and characteristic CT findings.
