Case in brief

A patient presented with a large anterior mediastinal teratoma measuring 11 × 10 × 10 cm, causing significant compression of the right atrium, right ventricle, superior vena cava, and aorta, along with perforation into the right pleural cavity and hemidiaphragm elevation. A median sternotomy was performed to address extensive adhesions, allowing for en bloc resection of the tumor and involved structures, which contained hair, fat, and calcifications.

Diagnostic / clinical pearl

Clinicians should be aware that mature mediastinal teratomas can present with extensive intrathoracic involvement, leading to significant cardiovascular and respiratory complications.
