Abstract

Infarction in the territory of the posterior choroidal artery(PChA) is rare. The main clinical manifestations of the PCHA infarction are known to be visual field defect, sensory-motor dysfunction, neuropsychological disturbances. Neuropsychological disturbances include of transcortical aphasia and amnesia. The latter disturbance is very rare and reported to be transient. We report a 77 year old man who presented with severe selective amnesia due to PChA infarction. Neurologic examination revealed right homonymous hemianopsia. Brain MRI showed infarction of PChA territory and multiple lacunes in the preventricular deep white matter.
