. Mediastinal cystic formations are well-shaped, often round that contain fluid and lined with epithelium. The main include congenital benign cysts (bronchogenic, duplicating the esophagus, neuroenteric, pericardial thymic cysts), meningocele, mature teratomas lymphangiomas. Many tumors (e.g., thymomas, Hodgkin's disease, germ cell tumors, mediastinal carcinomas, lymph node metastases, nerve ro...

Abstract 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 de novo atrial fibrillation, and very large intrapericardial mass. The underwent successful surgical resection, pathological findings conf...

Bronchogenic cyst is a benign congenital developmental abnormality of the embryonic foregut. It is usually formed as a result of an accessory lung bud becoming isolated from the rest of the trachea-bronchial tree. It is usually a solitary extra pulmonary cyst and is a benign condition found most commonly in the mediastinum with rare occurrence in the skin or subcutaneous tissues. The skin is a ...

We report a case of a 24-year-old man who presented with chest pain and electrocardiographic evidence of myocardial ischaemia. An abnormal structure located behind the heart on the urgent transthoracic echocardiogram and a computed tomography scan of the mediastinum led to prompt surgery with eventual resection of the lesion. The histology revealed fragments of connective tissue covered by squa...

Bronchogenic cysts are congenital foregut malformations thought to develop due to abnormal budding of tracheal diverticulumand proximal bronchial structures during embryologic development. The cyst is lined by ciliated pseudostratified columnar epithelium and the wall contains cartilage and layers of smooth muscle. These lesions most commonly are seen in the mediastinum, lung, or pleural spaces...
