Key result
Resection of a giant intrapericardial bronchogenic cyst completely resolves atrial fibrillation and heart failure symptoms.
Why the study?
Large intrapericardial bronchogenic cysts are very rare and must be considered in the differential diagnosis of heart failure with abnormal chest X-ray and atrial fibrillation.
Case Report (n=1)
No
May support resection for rare symptomatic intrapericardial cysts; hypothesis-generating given single case report.
BACKGROUND: Large intracardiac bronchogenic cysts are rare mediastinal masses. However, they must always be considered in the differential diagnosis of heart failure with abnormal chest X-ray. CASE PRESENTATION: We present a 60-year-old female patient with de novo atrial fibrillation, heart failure and a very large intrapericardial mass. The patient underwent successful surgical resection, with pathological findings confirming a bronchogenic cyst. CONCLUSIONS: Large bronchogenic cysts located intrapericardially are very rare. However, they should be included in the differential diagnosis of patients presenting with atrial fibrillation and heart failure with abnormal radiologic studies.

Maldonado-Escalante et al. (2021) conducted a case report in Giant intrapericardial bronchogenic cyst (n=1). Surgical resection was evaluated on Symptom resolution and echocardiographic improvement. Surgical resection of a giant 8x6 cm intrapericardial bronchogenic cyst resulted in complete resolution of atrial fibrillation and congestive heart failure symptoms.
