Abstract

The authors present 52 years old patient with arterial hypertension and diabetes, who developed cerebral ischemia in the vascularisation region of right posterior cerebral artery. Vascular damage of occipital and temporal lobes as well as thalamus caused left ipsilateral hemianopsia with preserved central field of vision. Riddoch phenomenon was found and documented as symmetrical optokinetic nystagmus. The patient experienced visual and auditory hallucinations, dèja vu phenomena, and unusual, never reported, somatognostic disturbances, appearing during sleep as a perception of his own left hand and leg which seemed to be deformed and unnaturally big. The authors discuss the relation of described symptoms with anatomical conditions (with special regard to ischemia of borderline regions), risk factors and secondary prophilaxy of ischemic stroke.
