A cystic mediastinal teratoma should be considered in the differential diagnosis of pericardial effusion causing cardiac tamponade.

May warrant considering mediastinal teratoma in tamponade differentials; leaves open generalizability from case reports alone.
We report the rare two cases of cardiac tamponade due to ruptured cystic teratoma. In both cases, a chest computed tomography scan showed large cystic mass with large amount of pericardial effusion. Transthoracic echocardiogram revealed cardiac tamponade physiology. En bloc resection of the mass was performed and pathologic examination showed mature cystic teratoma. The postoperative course of patients was uneventful. A cystic mediastinal teratoma should be considered in the differential diagnosis of pericardial effusion.

Kang et al. (2021) conducted a case report in Cardiac tamponade due to ruptured mature cystic mediastinal teratoma (n=2). Surgical en bloc resection of mediastinal teratoma was evaluated on Postoperative recovery without complication. En bloc surgical resection of ruptured anterior mediastinal mature cystic teratomas resulted in uneventful recovery without complications in 2 patients (100%) presenting with cardiac tamponade.
