They were treated surgically, There were 184 benign cases (85. 98% ), and 30 malignant cases (14.02 % ). Among them, there were 63 cases of neurogenic tumor (29.43 % ), 48 cases of thymic tumor (22. 4% ), 41 cases of teratoid tumor (19. 16% ), 12 cases of bronchial cyst (5. 61% ), and 9cases of intrathoracic adenoma of thyroid (4. 21%).

We report a case of a 14 ×8 mm right paracardiac cyst diagnosed at 20 weeks’ gestation. The prenatal evolution was uneventful and a magnetic resonance imaging at 31 weeks showed the limited extension of the cyst into the anterior mediastinum. At birth, the baby was asymptomatic, but the size of the lesion increased steadily (48 ×29 mm). At 7 months of life, he underwent a thoracoscopic resection of the cyst without intra or postoperative complications. Histological examination showed a lymphangioma. This case is remarkable for its prenatal diagnosis, the thoracoscopic treatment and the 8 years of followup without recurrence.展开更多
