気管支原性嚢胞は、胚発生時の前腸組織の異常な発芽に起因すると考えられている。縦隔気管支原性嚢胞の約90％は無症状であり、そのうちのごく一部は胸痛や呼吸困難を伴う。心嚢液貯留もその一つであるが，心膜炎はあまり報告されていない．我々は19歳女性の気管支原性嚢胞の1例を紹介する。心嚢液貯留を合併していた。気管支原性嚢胞の切除が予定されていたが、左心房に付着していたため部分的にしか切除できなかった。

Bronchogenic cysts are speculated to arise from abnormal budding of the foregut tissue during embryogenesis. Around 90% of mediastinal bronchogenic cysts are asymptomatic, and a small percentage of them present with chest pain and dyspnea. Pericardial effusion is one of the manifestations described; however, pericarditis has not been widely reported. We describe a case of a bronchogenic cyst in a 19-year-old female with an initial presentation of pericarditis due to mechanical impingement. There was an associated trace to small pericardial effusion. The bronchogenic cyst was planned to be excised; however, it could only be partially excised due to its adherence to the left atrium.
