Most of thesecysts are benign and asymptomatic in adults. However, some of them are clinically problematic due tothe compression of neighboring organs, infection, or perforation.CASE PRESENTATION: A 20-year-old man presented with severe dyspnea. Imaging revealed a mediastinalcyst in the subcarinal space compressing his right pulmonary artery and airway, which was later diag-nosed as a bronchogenic cyst. Due to quick symptom exacerbation, emergent cyst wall fenestration wasperformed through video-assisted thoracic surgery with “stand-by” extracorporeal membrane oxygena-tion. Complete cyst resection was difficult owing to adhesion of the cyst to the surrounding organs. Thesymptoms immediately resolved after surgery and the postoperative course was uneventful.CONCLUSION: Mediastinal bronchogenic cysts with life-threatening complications are rarely reportedin adults. However, this case was life-threatening due to airway and vascular compression; emergentsurgical care should be considered in such cases., International Journal of Surgery Case Reports, 64, pp.150-153; 2019}, pages = {150--153}, title = {A case of emergent operation for a life-threatening infectious mediastinal cyst}, volume = {64}, year = {2019} }
