摘要

A 58-year-old man with no relevant history presented with a right hemianopsia. Five hours before his admission, he developed flashing and shimmering lights in the right visual fields. Initial computed tomography (CT) revealed an area of hypodensity in the left occipital lobe in the distribution of the posterior cerebral artery (Figure 1). Besides the hemianopsia, the neurological examination was unremarkable. The clinic-radiological picture was suggestive of a stroke and he was admitted for additional investigations and management. CT angiography revealed no vessel occlusions and a perfusion CT revealed mild hyperperfusion in the affected region. Given the acuity of presentation, this was interpreted as ischemic stroke with spontaneous recanalization and compensatory hyperperfusion. During his first 24 h within hospital, he experienced a generalized tonic-clonic seizure and subsequent magnetic resonance imaging (MRI) showed a confluent hyperintensity in the left temporo-occipital region with a small area of restricted diffusion and no enhancement (Figure 1).
