Abstract:

A 37-year-old male presented to the neurology department after developing sudden headache, nausea, and visual disturbances. The patient had been diagnosed with hypertension 5 years previously, but was not currently taking appropriate medication; he also had a 20-pack/year history of smoking. At the time of admission, the patient’s blood pressure was 210/100 mmHg and remained high under continuous monitoring during the first 24 h. Two days later, he noted transient left leg weakness lasting approximately 2–3 min. Brain magnetic resonance imaging (MRI) revealed multiple bilateral hyperintense subcortical white matter lesions in the posterior circulation and the middle cerebral artery territories including the parieto-occipital lobes, temporal pole, and pons, on fluid-attenuated inversion recovery (FLAIR) sequence (Figure 1A). In addition, a focal hyperintense lesion at the right centrum semiovale was observed on diffusion weighted imaging and the lesion was confirmed as an acute ischemic cerebral infarction through low signal intensity on apparent diffusion coefficient map (Figure 1B). Magnetic resonance angiography of the brain revealed a saccular aneurysm 5 mm in diameter at the origin of the right middle cerebral artery bifurcation (Figure 1C). Several cerebral microbleeds in the left basal ganglia, bilateral occipital lobes, and pons were observed on susceptibility-weighted imaging (Figure 1D). The patient received antihypertensive treatment, and blood pressure was satisfactorily controlled within 7 d; his symptoms of headache, nausea, and visual disturbances also noticeably improved. Follow-up brain MRI was performed 4 months later and revealed near complete resolution of bilateral hyperintense lesions in the posterior circulation and the middle cerebral artery territories on FLAIR sequence (Figure 1E). We finally diagnosed the patient with posterior reversible encephalopathy syndrome (PRES)
