Spontaneous rupture of a cystic mediastinal teratoma complicated by superior vena cava syndrome.

Abstract

Spontaneous rupture of cystic mediastinal teratomas is rare but may cause serious complications. Here we report an unusual case of a cystic teratoma, which ruptured into the mediastinal and pleural cavities resulting in superior vena cava syndrome, acute mediastinitis, and pleural effusion. Early diagnosis and prompt surgical treatment of ruptured mediastinal teratomas are essential to preventing life-threatening complications.
