Computed tomography perfusion usefulness in early imaging diagnosis of herpes simplex virus encephalitis.

Acta Radiol; 47(8): 878-81, 2006 Oct.
Artigo em Inglês | MEDLINE | ID: mdl-17050372
An early diagnosis is crucial in herpes simplex virus encephalitis patients in order to institute acyclovir therapy and reduce mortality rates. Magnetic resonance imaging (MRI) is considered the gold standard for evaluation of these patients, but is frequently not available in the emergency setting. We report the first case of a computed tomography (CT) perfusion study that helped to establish a prompt diagnosis revealing abnormal increase of blood flow in the affected temporoparietal cortex at an early stage.
