[A case report of mediastinal cystic lymphangioma]

Abstract

Mediastinal lymphangioma is very rare in the literature. A resected case of mediastinal cystic lymphangioma was reported. A 41-year-old man admitted to our hospital complaining of sore throat. A chest X-ray examination showed a large mediastinal mass on the right. At the right thoracotomy, a large cystic mass filled the anterior mediastinum and extended from the thoracic inlet to the posterior costophrenic angle. The cyst contained about 600 ml yellowish brown fluid and was adherent to the surrounding tissue, especially to the aorta and the left main bronchus. The resected tumor was 20 x 12 x 10 cm in size and 620 g in weight. Histological diagnosis was cystic lymphangioma. The patient is alive and well 26 months later, and there is no sign of recurrence of the tumor.
