Esquistossomíase pulmonar aguda: achados na TCAR e apresentação clínica

Reversed halo sign in acute schistosomiasis

“…Schistosomiasis is a major helminthic infection in tropical and subtropical regions; it has affected an estimated 200 million people, resulting in considerable morbidity and occasional mortality. ( 1 - 3 ) In such regions, native populations and travelers are at risk of infection with Schistosoma spp. ( 2 ) The infection is acquired through direct contact with contaminated freshwater.…”

“…(2) The spread of infection requires an intermediate host-freshwater snails specific to each Schistosoma species-whose geographic distribution limits the distribution of the parasite. (3) Humans are colonized by three major species of the parasite ( 1 ) : S. mansoni , common in Africa, the Middle East, and South America; S. haematobium , common in Africa and the Middle East; and S. japonicum , common in Japan and China.…”

“…( 4 ) Early diagnosis and treatment of the disease are important to prevent severe late complications, such as pulmonary hypertension, cor pulmonale, and pulmonary arteriovenous fistulas. ( 1 )…”

“…A esquistossomose é uma infecção helmíntica importante em regiões tropicais e subtropicais; estima-se que já tenha afetado 200 milhões de pessoas, com morbidade considerável e mortalidade ocasional. ( 1 - 3 ) Nessas regiões, tanto as populações nativas como os viajantes correm risco de infecção por Schistosoma spp. ( 2 ) A infecção é adquirida por meio de contato direto com água doce contaminada.…”

Human Schistosome Infection and Allergic Sensitisation

“…Acute schistosomiasis is a debilitating febrile disease which often occurs in individuals with no experience of infection. It is characterized by high percentage of eosinophilia, which may be reversed by chemotherapy [205], nausea, urticaria, dry cough, and fever [206, 207]. Anatomically, this stage is accompanied by a dissemination of large and destructive granulomas around the eggs [67, 208].…”
