Abstract

Background: Acute bilateral blindness is an uncommon phenomenon that requires immediate diagnosis and action. The emergent evaluation should concentrate on an early distinction between ocular, cortical, and psychogenic etiologies.

Objective: To present a case of cortical blindness without anosognosia due to the embolic occlusion of both posterior cerebral arteries (PCAs) and treated by intravenous and mechanical thrombolysis.

Case Report: A 67-year-old woman was admitted to the Stroke Unit due to cortical blindness without anosognosia. At the admission to the hospital, an emergent computed tomography scan of the brain ruled out intracranial acute hemorrhage and showed subtle changes consistent with hyperacute ischemia of the left occipital cortex, while a CT angiography demonstrated the occlusion of the P3 segment of both right and left posterior cerebral arteries. The patient was treated with combined thrombolysis (intravenous and mechanical thrombolysis), obtaining complete revascularization and a significant clinical improvement.

Conclusion: Even if there is no randomized controlled trial to compare the effectiveness and safety of mechanical thrombectomy (MT) to intravenous thrombolysis in patients with posterior circulation occlusion, the good outcome of this case encourages combined stroke treatments in posterior circulation stroke, even in case of mild but disabling neurological deficits.

Keywords: Cortical blindness, posterior cerebral artery, alteplase, mechanical thrombolysis, Penumbra 4Max, stent retriever, case report.
