Humanes Parechovirus Meningoenzephalitis

Magnetic

resonance imaging patterns of paediatric brain infections: a pictorial review based on the Western Australian experience. Restricted diffusion in supratentorial white matter—diffuse (Pattern 1A). 2-day-old term infant with generalised seizures and CSF-proven parechovirus encephalitis. DWI (a, b) demonstrated a striking pattern of restricted diffusion involving deep and periventricular white matter. On T2-weighted imaging (c), corresponding foci of low signal intensity were relatively subtle (arrows). A follow-up scan 5 weeks later (d) revealed significant tissue loss with areas of cystic encephalomalacia
