There is a 37 x 65mm heterogeneous, partially calcified pleurally based mass in the left hemithorax abutting the proximal descending aorta. The mass partially erodes the posterior forth and fifth ribs and there is periosteal reaction on the anterosuperior edge of the forth rib. The mass is closely related to the intervertebral foramen of T4 and T5 however it is not widened.
Subpleural ground glass opacity in the lingular segment of the left upper lobe is of uncertain significance. Mild dependent right sided atelectasis.
Prominent mediastinal lymph nodes without lymphadenopathy by size criteria.
