Figure 1. Magnetic resonance imaging of the brain of a 28-year-old woman (patient 1) who had neurologic complications of influenza B virus infection, Romania. A) Axial T2 image showing multiple areas of T2-associated hyperintense lesions with involvement of the genu corpus callosum, bilateral internal capsule, and several areas of white matter in the right frontal lobe, and more discreetly at the limit between the right parietal and occipital lobe. B) Axial diffusion-weighted image showing restricted diffusion associated with lesions. C) Coronal fluid–attenuated inversion recovery image showing multiple hyperintense lesions in the right caudate head and the cortical and deep white matter of the frontal lobes. D) Coronal diffusion-weighted image showing restricted diffusion associated with lesions.
