case_images: a. Chest X-ray showing an enlarged mediastinal shadow, left atelectasis, and pleural effusion. b. Chest computed tomography showing a large anterior mediastinal tumor, tracheal and cardiovascular compression, left pleural effusion, and atelectasis. The image is rotated because the patient's respiratory distress was only relieved by placement in the left lateral decubitus position.

case_images: The patient's chest X-rays showed enlarged mediastinal shadows and left lung atelectasis (Fig. 1a). Chest computed tomography (CT) revealed left atelectasis and pleural effusion and a giant anterior mediastinal tumor that markedly compressed the adjacent cardiovascular structures and the trachea (Fig. 1b).

case_images: T-cell lymphoblastic lymphoma, and chemotherapy was administered. Three months later, we could remove the stents because the tumor size was substantially reduced (Fig. 2).

case_images: His chest CT showed a giant tumor with a contrast effect in the anterior mediastinum, and, although tracheal and bronchial contractions were observed, complete occlusion had not occurred (Fig. 3).

case_images: Before the biopsy, we placed a Dumon Y stent at the tracheal bifurcation (Fig. 4), performed endotracheal intubation, and confirmed that ventilation was possible.
