ABSTRACT
BACKGROUND: Paragonimiasis is a parasitic disease that typically produces a subacute to chronic inflammatory disease of the lung. Although rare in the United States, paragonimiasis is sporadically observed in the immigrant population. Rarely, paragonimiasis can affect the nervous system. This infection is even more unusual in the pediatric population, and therefore can be challenging to diagnose. PATIENTS: Here we present a child with cerebral paragonimiasis. She presented with new onset seizures in the setting of a febrile illness. Magnetic resonance imaging of the brain with contrast revealed a ring-enhancing lesion within the right frontal lobe and a second lesion in the left parietal lobe extending from the cortex to the centrum semiovale. Extensive evaluation including stool ova and parasite analysis confirmed the diagnosis of Paragonimus westermani. She was treated with praziquantel and prednisone and improved both clinically and radiographically. CONCLUSIONS: Cerebral paragonimiasis is diagnosable and treatable and therefore is important to consider in the differential of immigrants presenting with cavitary lung lesions and central nervous system findings.
