Giant Mediastinal Teratoma in a Child: A Case Report With a Brief Review of the Literature

Figures

• 

  FIGURE 1. Anteroposterior chest radiograph on admission. Marked mediastinal widening is present with a large homogeneous opacity occupying most of the left hemithorax and causing rightward deviation of the trachea and mediastinum. Cardiac contours and the left hilum are not clearly delineated, suggesting mass effect and displacement by a voluminous mediastinal lesion.

• 

  FIGURE 2. Contrast‐enhanced axial chest CT showing a large, well‐circumscribed mediastinal mass measuring approximately 15.9 × 14.1 cm (maximum axial dimensions). The lesion is predominantly of fluid attenuation, occupies nearly the entire left hemithorax, and produces marked rightward deviation of the mediastinum, compression of the contralateral lung parenchyma, and complete left lung atelectasis.

• 

  FIGURE 3. Surgical specimen immediately after extraction. The specimen is a large solid‐cystic mass with a thickened capsule; on opening, dark serous fluid, sebaceous materials, and solid components were evident.

• 

  FIGURE 4. Postoperative chest CT (control). Adequate bilateral pulmonary expansion is demonstrated with complete re‐expansion of the left lung, a centrally located mediastinum and no residual mediastinal mass or pleural/mediastinal collections.
