A 40-year-old woman noticed blurred vision of the right eye. The optic disc edema of bilateral eyegrounds was noted, and brain MRI showed abnormal signals of the brainstem at a neurosurgical clinic. On her first visit, blood pressure was as remarkably high as 250/130 mmHg. Neurologically, only optic disc edema of bilateral eyegrounds was found. Both T2-weighted MRI and FLAIR showed hyperintense signal areas mainly from the ventral pons to medulla oblongata. These areas were not enhanced with gadolinium. About three weeks after the administration of an antihypertensive agent, brain MRI revealed no abnormal signal. About three months later, the blurred vision disappeared and ophthalmological abnormalities subsided. We diagnosed her with a brainstem variant of RPLS, presenting with visual disturbance caused by hypertensive retinopathy.
