case_images: Diagnostic assessment: the chest X-ray showed mediastinal enlargement with left para-cardiac opacity (Figure 1).
case_images: frontal computed tomography: (A) mature teratoma of the superior mediastinum; axial computed tomography; (B) mature teratoma of the anterior mediastinum; sagittal computed tomography; (C) mature teratoma that compresses the trunk of the pulmonary artery (arrow)

case_images: The chest computed tomography scan (CT) objectified a voluminous anterior and upper mediastinal cystic formation lateralized to the left of 9x7.2x6 cm with a compression effect on the trunk of the pulmonary artery (Figure 2).

case_images: The exploration found a mediastinal mass of 9 cm of major axis, related to the lateral face of the aorta, with the trunk of the pulmonary artery and very adherent to the pericardium (Figure 3).
