[An intrapulmonary hematoma induced by a Swan-Ganz catheter].

A case of circumscribed intrapulmonary haematoma induced by a balloon-tipped catheter is presented in a 56 year old patient with coronary heart disease. The bleeding site appeared as a pulmonary circular focus or coin-shaped lesion on the chest radiograph. The authors discuss possible causes and risk factors of intrapulmonary haematomas and differential diagnosis of pulmonary coin-shaped lesions.
