Diffusion-weighted imaging proves watershed infarction in neurotrichinosis

Central nervous system involvement in trichinosis is rare. Computed tomography (CT) findings in neurotrichinosis are well described, but there are only a few reports about magnetic resonance (MR) appearances. Several pathological mechanisms have been suggested to explain neurological complications. Using sequential diffusion-weighted and conventional MR imaging, we were able to demonstrate bilateral watershed infarction due to eosinophilic vasculitis as the underlying cause of CNS involvement.
