Mesothelial Cyst of the Posterior Mediastinum: A case report / 대한흉부외과학회지

ABSTRACT

Mesothelial cyst is a rare mediastinal tumor and usually presents in the right cardiophrenic angle. However, it sometimes occurs in atypical locations and it's locating in the posterior mediastinum, especially, is very rare. A large cystic mass of the posterior mediastinum between pericardium and vertebral body was incidentally recognized in a patient of a 30-year-old woman admitted due to traffic accident. Even though it was very large in size measuring 18 cm at longest diameter and is extending mainly to the left pleural cavity, she had no symptomatic complaints. Complete excision was performed through video-assisted thoracoscopic surgery with a additional small working window, which was necessary for dissecting the deepest point to the right pleural cavity. She is in good condition without recurrence on long-term follow-up.
