A 56-year-old man was introduced to our hospital because of an abnormal shadow found on a chest X-ray. Chest CT and MRI revealed a cystic lesion in the anterior mediastinum, and a thymic cyst was clearly visible.
The cyst was defined from the surrounding tissue by pneumomediastinum prior to VATS. It was completely situated in the anterior mediastinum without any connection to the neck. En -bloc resection of the left lobe of the thymus was performed. The lesion was pathologically diagnosed as a parathyroid cyst.
The mediastinal parathyroid cyst was easily resected using VATS.
