Human immunodeficiency virus encephalitis.

Here, we present a case of pyrexia with altered sensorium in a young healthy male individual. On evaluation, he was detected to have human immunodeficiency virus infection with low CD4. He had no opportunistic infection or any other acquired immunodeficiency syndrome-defining illnesses although his magnetic resonance imaging brain showed features of encephalitis. He recovered tremendously within 3 months of antiretroviral therapy.
