Epicardial mesothelial cyst originating from the roof of the left atrium: a case report.

ABSTRACT:

Background

Epicardial mesothelial cysts are cysts that are attached to the epicardium within the pericardial cavity. Reports on epicardial mesothelial cysts are rare, and limited studies have investigated their surgical management. Here, we report the rare case of an epicardial cyst originating from the roof of the left atrium.

Case summary

A 73-year-old man with dyspnoea on exertion and lower limb oedema was diagnosed with a giant cyst (diameter, 7 cm × 4.5 cm) in the pericardial cavity using computed tomography. Off-pump surgery was performed with successful resection of the cyst with a pedicle connected to the roof of the left atrium. Histological examination confirmed the mesothelial origin of the tumour cells.

Conclusion

Cysts rarely develop within the pericardia
