Background:
Infections of the central nervous system might present in an acute form such as to be similar with the clinical characteristics of a stroke. This situation will hamper a correct diagnosis and a prompt treatment that can otherwise be successful.
Case description:
We present the case of a herpes virus encephalitis that came up in the emergency department with an admission diagnosis of ischemic cerebral accident. Being the symptomatology unclear, the findings of magnetic resonance of the brain oriented versus an infectious disorder. The lumbar tap confirmed the presence of herpes simplex virus (HSV) 1 virus and an antiviral therapy was administered, leading to resolution of the condition within the 3 weeks of hospitalization.
Conclusion:
HSV infections may mimic stroke and therefore should be included in the differential diagnosis of atypical acute nervous conditions. In neurological events of acute nature, especially in febrile patients whose brain imaging is suspicious or inconclusive, the eventuality of a herpetic encephalitis should be kept in mind. This will lead to a prompt antiviral therapy and to a favorable outcome.
