[Autochthonous pulmonary dirofilariasis in Europe].

The chest X-ray of a 39-year-old woman who had an acute onset of fever, cough, dyspnoea and thoracic pain revealed two peripheral round opacities (about 1.5 cm in diameter) in the right lower lobe. Extensive further studies having failed to discover the cause, a diagnostic thoracotomy was performed and the two pleura-adjacent tumours were removed. Histological examination revealed granulomatous encapsulated filariae, species Dirofilaria immitis. This was confirmed by a positive ELISA test with Dirofilaria immitis antigen. As the patient had been on holiday in Corsica three months before onset of symptoms, it is most likely that the pulmonary dirofilariasis was acquired autochthonously in Europe.
