Abstract
Background Teratoma is a tumor derived from fetal germ cells with aberrant differentiation.
Case Description A 3-month-old infant with a mediastinal tumor was referred to our heart center. She
presented with progressive dyspnea, cyanosis, and the need to be manually ventilated.
The computed tomography scan displayed a huge tumor restricting the distal trachea
including the bifurcation. An emergent operation was performed and the tumor was completely
removed. Histological examination confirmed a mature teratoma.
Conclusion In such life-threatening situation, the early detection and the immediate operation
are very important for the management of rapidly-progressing mediastinal teratomas
compressing the respiratory tract.
