Testicular choriocarcinoma revealed by a localized pulmonary edema: a case report.

We report the case of a young man hospitalized because of an acute pulmonary embolism presenting as a focal pulmonary edema, without evidence of left ventricular failure. This pulmonary embolism was caused by a testicular choriocarcinoma that entailed both a neoplastic venous involvement with pulmonary neoplastic embolism, and a compression of inferior vena cava with thrombosis and subsequent pulmonary thromboembolism. This case combines two unusual associations: (i) Pulmonary embolism causing a localized pulmonary edema, (ii) Neoplastic pulmonary embolism of a testicular choriocarcinoma.
