[Unilateral pulmonary edema, pneumopericardium and bronchial cancer (author's transl)].

Carcinoma of the bronchus was detected following the onset of cardiac rhythm disorders, and a pneumopericardium with associated, radiologically detected, unilateral pulmonary edema. The tumor extended mainly around the bronchus and in the mediastinum, and a bronchopericardial fistula was present together with invasion of the left auricle and pulmonary veins. Pneumopericardium is a rare lesion and it is exceptional to observe it during the course of bronchial cancer.
