[Acute respiratory insufficiency in parasitic eosinophilic pneumonia].

We report a case of bilateral eosinophilic pneumonia in a 33 year old man. This case developed rapidly into acute respiratory failure and required artificial ventilation. Intravenous corticosteroid therapy produced a rapid improvement in the clinical picture. There was hyper-eosinophilia in both the blood and the alveoli which leads to a search for a parasitic aetiology. The different parasitic serologies were negative except for Toxocaracanis. The ELISA index was strongly positive at 2,597. Treatment with thiabendazole was started.
