A rare case of mediastinal cavernous lymphangioma in an adult

Abstract

Mediastinal cavernous lymphangioma is an extremely rare benign tumor. A 17-year-old female was referred to our hospital due to the finding of a right paratracheal lesion with enlargement of the upper mediastinum on a chest radiograph. Computed tomography of the chest showed a 4-cm, well-circumscribed cystic mass in the anterior mediastinum. We conducted video-assisted thoracoscopic excision of the cyst. The final pathology report revealed a cavernous lymphangioma. As incomplete resection can result in recurrence, an appropriate surgical procedure for complete resection should be performed based on accurate preoperative evaluation. This is the first documented case of a complete mediastinal cavernous lymphangioma resected using the VATS technique.
