Mesothelial cyst is one of the congenital mediastinal cystic lesions. It is essentially a unilocular cyst filled with clear or slightly yellowish thin fluid. It can be classified as a pericardial cyst when it is attached to the pericardium and as a pleural cyst when it is in other mediastinal locations. Mesothelial cyst have a fibrous wall of varying thickness, and microscopic examination of the wall reveals a single or multi layer of mesothelial cells resting on a loose stroma of connective tissue. It is reported that this cyst is frequently located at the cardiophrenic angle. It is difficult to diagnose anterior superior mediastinal cystic lesions preoperatively. So operative treatment is indicated for diagnosis and therapy. Thoracoscopic resection is less invasive than usual thoracotomy and indications are numerous. We successfully performed thoracoscopic complete resection of a mesothelial cyst.
