MRI findings from a case of fulminating adult-onset measles encephalitis.
We report a rare case of fulminating adult-onset measles encephalitis. A 34-year-old man developed a comatose state after measles eruptions and ultimately akinetic mutism. Titers of anti-measles IgM antibodies were elevated in both serum and cerebrospinal fluid. Brain magnetic resonance imaging (MRI) 3 months after onset revealed widespread hyperintense lesions in the periventricular white matter and marginal hyperintense lesions in the brainstem on fluid-attenuated inversion recovery and diffusion-weighted images. The marginal lesions in the brainstem are similar to subpial demyelinating lesions seen in postinfectious encephalomyelitis. This case of encephalitis may be related to an autoimmune-mediated process triggered by measles infection.
