title: Clinical and radiologic manifestations of H1N1 virus infection associated with neurological complications: a case report.
abstract: Encephalitis complicating novel influenza A (H1N1) viral infection is rare and has only been reported in children. We present cerebral magnetic resonance imaging findings from a confirmed adult case with H1N1 infection who presented with acute encephalitis and subsequent respiratory failure. Cerebral magnetic resonance imaging showed hyperintense abnormalities in the bilateral globus pallidus in T1-weighted images, and multiple hyperintense abnormalities in the right insular cortex, right parahippocampus, and the pontine tegmentum in fluid-attenuated inversion recovery images.
