Intrapericardial bronchogenic cysts.

Abstract

A rare case of large intrapericardial bronchogenic cyst with superior vena caval obstruction is reported. The cyst was successfully removed and the superior vena cava, which was narrowed by pressure fibrosis and thrombosis, was reconstructed satisfactorily and has maintained patency. In another case a large cyst of the same type without vena caval obstruction was successfully treated surgically. The features of these 2 cases are compared with those of 20 reported cases. The angiographic data in these cases appear to be sufficiently characteristic to suggest the nature of the lesion and the clinical finding of pericarditis early in the course of the disease may also suggest the diagnosis.
