Abstract
|
|
|
|
Hypertensive encephalopathy is characterized by various neurological symptoms including severe hypertension. The classic magnetic resonance imaging markers of hypertensive encephalopathy are symmetric high signal intensities in the subcortical parieto-temporo-occipital regions on T2-weighted imaging and fluidattenuated inversion recovery imaging. Two-thirds of patients display this high signal intensity in the frontotemporal lobes, and high signal intensity in the brainstem, cerebellum, or basal ganglia is rarely observed. We report a rare case of atypical hypertensive encephalopathy involving the brainstem and thalamus. Since similar imaging features, as seen in hypertensive encephalopathy, can be seen in other conditions such as infarction, rhombencephalitis, and brain neoplasms, it is important to include hypertensive encephalopathy as one of the differential diagnoses.
