title: Recurrent scintillating scotoma and homonymous hemianopia due to metastatic melanoma.
abstract: Acute left homonymous hemianopia and recurrent scintillating scotoma occurred in a 43-year-old woman due to metastases from a cutaneous malignant melanoma that had been resected 5 years previously. Computed tomography initially demonstrated small, probably embolic, areas of occipital lobe infarction. Five months after the onset of her visual symptoms, massive cerebral hemorrhage occurred from a large right occipital lobe tumor that had not been present initially. Autopsy demonstrated malignant melanoma. Visual symptoms related to tumor embolization and/or cerebral hemorrhage may be the presenting features of metastatic cutaneous malignant melanoma.
