There is a large saccular aneurysmal dilatation of the aortic arch measuring 5.5 (AP) x 5.3 (ML) x 8.4 (CC) cm. Presence of intramural haematoma mainly at the superior aspect. It displaces the trachea to the right side. The aneurysm is in close proximity with the oesophagus but no clear communication seen between these structures. No blood products in the oesophagus. No contrast extravasation or haemothorax to suggest ruptured aneurysm. Left common carotid and subclavian arteries are normal.
A cavity with surrounding consolidation seen in the right middle lobe. Aneurysmal branch arising from the right middle lobe pulmonary artery seen within the cavity suggestive of Rasmussen aneurysm. Haematoma seen surrounding the aneurysm.
Tree-in-bud appearance and numerous tiny nodules seen in the right middle and lower lobes indicating active endobronchial infection.
