[Pulmonary manifestations of schistosomiasis]

Pulmonary manifestations are not frequent. They may occur at any stage of the parasitic cycle. Acute manifestations are concurrent with the parasitic toxemia stage and suggests an immunoallergic mechanism. Acute pulmonary heart is exceptional. Chronic manifestations are the consequence of egg-laying and are dominated by chronic pulmonary heart. Treatment is based on current antischistosomal drugs but their effectiveness is only evident in parasitic toxemia stages.
