Three patients with trichinosis developed central nervous system complications. Cerebral computed tomography showed multifocal hypodense lesions in two patients. The lesions were associated with contrast enhancement and cortical gyral enhancement in the first case, suggesting hypoxia and infarction. In the second patient, magnetic resonance imaging showed multiple high-signal-intensity lesions. Early cerebral computed tomography was normal in the third patient. All patients recovered after treatment with antiparasitic drugs and corticosteroids. We suggest that neurologic complications of trichinosis should be treated by corticosteroids and flubendazole.
