Mediastinum: A large soft tissue mass in the left anterior mediastinal measures up to 8.3 x 6.5cm in the axial plane and extends into the left hemithorax.. In the craniocaudal axis, the mass extends from the medial aspect of the left hemidiaphragm cranially beyond the thoracic inlet to the level of the thyroid gland. In the superior mediastinum, the mass encases both brachiocephalic and left subclavian and left common carotid artery and the proximal large veins and results in rightward displacement of oesophagus and trachea. The mass encases the left main bronchus and lies just anterior to the left bronchus intermedius. No hilar, axillary or subclavian lymphadenopathy. There is probable involvement of both left recurrent laryngeal and phrenic nerves.
Chest: Minor groundglass change in the perihilar region of the left lower lobe. The lungs and pleural spaces are otherwise clear. In particular, there are no pulmonary parenchymal nodules or nodes identified.
