A 15-year-old boy developed persistent fever and a diffuse maculopapular rash 21 days before admission to hospital. He was treated with anibioics and symptomaic drugs without improvement. Clinical examination revealed a well developed underweight teenager, with pale skin. His axillary temperature was 39.3ºC. There was no history of diarrhea. Abdominal palpaion showed painful hepatomegaly and splenomegaly. Leukocytosis (38,000 cels/mL) and eosinophilia (30,400 cels/mL) were found in a rouine blood count. Platelet counts and hemoglobin levels were within the normal range and serum alanine aminotransferase was slightly elevated. Abdominal ultrasound showed liver and spleen enlargement and periportal lymph nodes. Schistosoma mansoni eggs were described in the stools. He reported contact with stream water in an endemic area for schistosomiasis 30 days before the start of symptoms. A chest helical computed tomography (CT) scan with muliplanar reconstrucion and maximum intension projecion (MIP) technique demonstrated bilateral scatered nodules and consolidaion in let upper lobe (Figure A). A sagital reconstrucion of let lung showed two consolidaions in upper and lower lobes (Figure B; arrows).

O paciente, de 15 anos, desenvolveu febre e erupção cutânea maculopapular difusa 21 dias antes da admissão hospitalar. Ele fez uso de anibióicos e sintomáicos sem melhora do quadro. Ao exame clínico, o adolescente aparentava bom desenvolvimento somáico e encontrava-se emagrecido. A pele era pálida e a temperatura axilar elevada (39,3ºC). Não havia relato de diarréia. O ígado e o baço eram palpáveis e dolorosos. O hemograma revelou leucocitose (38.000 células/mL) e eosinoilia (30.400 células/mL); a contagem de plaquetas e o nível de hemoglobina eram normais. A alanina-aminotransferase estava ligeiramente aumentada no soro. A ultrassonograia abdominal conirmou aumento do ígado e do baço e ideniicou linfonodos periportais. No exame parasitológico das fezes, havia ovos viáveis de Schistosoma mansoni. O paciente relatou contato com águas naturais em área endêmica para esquistossomose 30 dias antes do adoecimento. Tomograia computadorizada (TC) helicoidal com reconstruções multiplanares e técnica MIP (maximum intension projecion) demonstraram nódulos esparsos bilaterais e consolidação no lobo superior esquerdo (Figura A). Na reconstrução no plano sagital, observou-se no pulmão esquerdo duas consolidações pulmonares nos lobos superior e inferior (Figura B; setas).
