Abstract
Cystic lymphangioma mainly occurs in children. Cystic mediastinal lymphangioma (CML) originates from mediastinal tissues and is an extremely uncommon cystic lymphangioma that develops from the lymphatic vessels. The present study reports the case of 46-year-old male patient with a giant CML that was surgically resected by video-assisted thoracoscopy. The largest diameter of the CML was 18.0 cm, and ~400 ml of pale yellow fluid was removed from the cystic cavity during surgery. The postoperative pathological reports on the cystic wall showed that the neoplasm was a CML. At present, at the one-year postoperative follow-up, there are no signs of recurrence. In conclusion, complete surgical resection may prevent recurrence.

Summary
Known as cystic hygroma, is a congenital malformation originating from lymphatic hyperplasia. Cystic lymphangioma is a type of hamartoma and verges on the clinical boundary between tumor and deformity. The majority of lymphangiomas are observed in patients under the age of five [1], with extremely few cases reported in adulthood. This disease can occur in various areas of the body, with the most common location being the neck. Cystic mediastinal lymphangioma (CML) is an extremely uncommon benign cystic lymphangioma developed from the lymphatic vessels. CMLs are most often located in the anterior mediastinum. The present study reports the case of a giant anterior CML for this purpose.
