Schistosomiasis is a helminthic infection that is endemic in tropical and 
subtropical regions. Pulmonary involvement can be divided into two categories: 
acute or chronic compromise. Chronic and recurrent infection develops in persons 
living or travelling in endemic areas. In the lungs, granuloma formation and 
fibrosis around the schistosome eggs retained in the pulmonary vasculature may 
result in obliterative arteriolitis and pulmonary hypertension leading to cor 
pulmonale. Acute schistosomiasis is associated with primary exposure and is 
commonly seen in nonimmune travelers. The common CT findings in acute pulmonary 
schistosomiasis are small pulmonary nodules ranging from 2 to 15 mm and larger 
nodules with ground glass-opacity halo. Katayama fever is a severe clinical 
manifestation of acute involvement. We present a case of pulmonary involvement 
in schistosomiasis and provide a discussion about typical imaging findings in 
the acute and chronic form.
