title: [A case of giant mediastinal cystic lymphangioma].
abstract: A 13 year-old boy was admitted because of anterior chest pain, fever up and exertional dyspnea. Chest X-ray film showed a large mass shadow on the middle and lower lung field with positive silhouette sign. Under the ultra-sonic tomogram the mass showed cystic pattern with septum. The bloody fluid collected by puncture suggested hemorrhage into the cyst. Chest CT scan revealed a well defined cystic mass in the left thoracic space. The mass reached to the right thoracic space through behind the Inferior Vena Cava (IVC). At operation, although the tumor adjoined heart, esophagus, diaphragma and IVC, it was removed completely. Pathological diagnosis was cystic lymphangioma.
