Imaging before treatment. (a) Chest X-ray showing a large mediastinal mass in the region of the superior mediastinum and the patient was intubated. (b) CT showing a large soft tissue density mass lesion and is resulting in compression of the superior vena cava and was slit-like on the axial image (red arrow). (c) CT coronal reformation redemonstrating a large soft tissue density mediastinal mass.

CXR showed widened mediastinum involving the paratracheal strip and no evidence of atelectasis, unilateral hyperinflation, or cardiomegaly. Chest computed tomography revealed anterior and superior mediastinal mass compressing the SVC, with narrowing of lumen of the ascending aorta, transverse arch, and descending aorta, as well as obliteration of the main bronchus and its branches [Figure 1].
Imaging after treatment. (a) Chest X-ray showing reduced size of the superior mediastinal mass and endotracheal tube was removed. (b) CT showing reduction in the size of soft tissue density mass lesion in the superior mediastinum. There was a significant improvement in earlier seen compression of SVC and now showing better caliber on the axial image (red arrow). (c) CT coronal reformation showing reduction in the size of earlier seen mediastinal mass.

Repeat CXR was normal and follow-up chest CT showed normal caliber unobstructed SVC, aorta, main bronchus, and its branches [Figure 2].
