Presentation
Shortness of breath following MVA.
Patient Data
There is large defect at the right hemidiaphragm measuring 143 × 87 mm in size, accompanied by partial herniation of the liver through the defect. Passive collapse is present at the lower zone of the right lung. Mild right-to-left displacement of the heart is observed due to the pressure effect of the herniated liver. Focal atheromatous aortic bulge involving the anteromedial aorta near the isthmus is compatible with a ductus diverticulum. Pseudo-aneurysm could be considered as a differential.
Case Discussion
Differentiation of an aortic pseudoaneurysm versus a ductus diverticulum is critical, particularly in the setting of trauma.
