انسفالیت، التهاب مغز (انسفالیت)
Meningitis and encephalitis can be life threatening neuro- logic emergencies that require critical care management.
Early recognition and treatment particularly of bacterial menin- gitis and herpes encephalitis can improve patient outcomes.
ENCEPHALITIS
Encephalitis manifests with fever, headache, and alteration of consciousness.
Nuchal rigidity may be present in a mixed meningoencephalitis picture but should be absent in isolated encephalitis.،HSV infection within the central nervous system (CNS) is one of the most common viral causes of encephalitis in the United States.
This occurs most commonly in patients between 20 and 50 years of age and HSV encephalitis carries a mortality rate >70% if left untreated.
Temporal lobe lesions on CT scan or MRI are suggestive of HSV encephalitis and cerebrospinal fluid analysis may demonstrate a lymphocytic pleocytosis and/or erythrocytosis.
Rash involving multi- ple dermatomes or crossing the midline may represent disseminated dis- ease, which can occur in immunocompromised patients when the virus spreads to visceral organs to cause pneumonitis, hepatitis, or encephalitis.
plications such as encephalitis, meningitis, and Guillain-Barre syndrome
