Abstract

Hypertensive encephalopathy is characterized by an acute, severe rise in blood pressure associated with headache, nausea, vomiting, altered mental status, and focal neurologic deficits, and rapid improvement after control of blood pressure. An eight-year old boy had been admitted with symptoms of red urine, fever, headache, convulsion, and visual blurring of vision. Blood pressure was 140/90mmHg, and CSF exam revealed WBC 8/mm3, glucose 83mg/dL, protein 106mg/dL. Serum C3 was 8mg/dL, C4 17mg/dL, ASO 1,024 Todd units. Brain CT showed non specific findings, however, MRI revealed symmetric high signal intensity lesions on T2WI over the parieto-occipital areas bilaterally. These lesions had been completely resolved on the following MRI 4 weeks later.
