[Pericarditis in bird raiser's disease (author's transl)].

The authors report the case of a 53 years-old male who was presenting signs of a chronic interstitial pneumonitis. A pericarditis was found and the ECG abnormalities first disappeared, then reappeared with new exposure to birds, before making the diagnosis of bird raiser's lung on the history and the immunologic findings. The possibility of pericardial involvement during bird raiser's lung or farmer's lung is found in 4 previously reported cases.
