Presentation
Chest pain and cough 3 weeks ago
Patient Data
There is a large dissecting aneurysm involving the descending thoracic and upper abdominal aorta. The intimal flap appears extending distal to the origin of the left subclavian artery and terminating distal to the origin of renal arteries. The dissecting aneurysm measures about 8 cm along its maximum caliber, 32 cm in length. The false lumen is thrombosed till the origin of SMA, then it is faintly enhanced distally. The true lumen (denser) supplies the celiac trunk, SMA, and left renal arteries. The dissection extends to the right renal artery with evidence of diminished blood flow and atrophic renal changes. The left bronchus was seen narrowed by the large aortic dissection with subsequent total left lung collapse.
Case Discussion
The patient presented with left chest pain and cough 3 weeks ago. His only past medical history included asthma and his vitals were non-significant.
CT chest with contrast identified Stanford type B dissection starting from descending thoracic and involving the abdominal aorta.
