[Secondary neoplastic subacute constrictive pericarditis disclosing a bronchial cancer].

In a fifty-three-year-old man, constrictive metastatic carcinoma of the pericardium revealed a bronchial carcinoma. The subacute course was rapidly progressive. Only partial pericardiectomy could be performed. Death occurred 16 days after the peripheral signs of compression of the heart became patent. In such cases early diagnosis, before signs of constrictive pericarditis become obvious, is very important.
