The importance of MRI in the acute phase of herpes encephalitis mimicking an acute ischemic stroke.

The diagnosis of herpes simplex encephalitis (HSE) can present challenges for neurologists and neuroradiologists due to its variable clinical presentation and atypical radiological features. Brain magnetic resonance imaging (MRI) plays a crucial role by identifying some mimicking conditions, including ischemic strokes, through the accurate interpretation of specific sequences. This report highlights a case of misdiagnosed HSE, aiming to discuss the management of similar cases and underscore the relevance of MRI in the emergency setting.
