A case of adult influenza A virus-associated encephalitis: magnetic resonance imaging findings.
A 27-year-old man presented with fever, convulsive seizure, and sudden impairment of consciousness. Magnetic resonance imaging (MRI) abnormalities were found in the bilateral thalami, including the brain stem and white matter. The possibility of a previous influenza A virus infection was considered, and cerebrospinal fluid cells and interleukin-6 were elevated. The MRI findings closely resembled those found in cases of childhood acute necrotizing encephalopathy (ANE). The present case suggests that adult influenza A virus-associated encephalitis/encephalopathy or ANE can occur during winter influenza epidemics.
