Dide-Botcazo syndrome due to bilateral occlusion of posterior cerebral artery.

Dide-Botcazo syndrome is a rare clinical syndrome characterized by a combination of cortical blindness with anosognosia for blindness, amnesia and topographical disorientation, secondary to bilateral occipital cortex lesions also involving the infero-medial temporal lobe structure. We report a case of a man who acutely presented confusion and cortical blindness. The cerebral angiography demonstrated bilateral occlusion of posterior cerebral artery (PCA). Sequential intravenous (i.v.) and intra-arterial (i.a.) thrombolysis were ineffective and the patient developed a complete Dide-Botcazo syndrome.
