Angio-imaging was performed in 10 patients (3 CTA, 7 catheter angiography).
On follow-up catheter angiography, the pseudoaneurysm was markedly decreased in size with only trace filling of a subcentimeter residual pseudoaneurysm sac.
Although the most common mass in this location would be a schwannoma, these rarely hemorrhage or have intratumoral hemorrhage and are typically hypovascular to avascular on catheter angiography [4].
Despite great advances in imaging technology, such as CTA, MRI, and MRA, conventional catheter angiography remains the gold standard for diagnosis of vascular abnormality.
Further, catheter angiography can be added to MRA when clinically warranted.
The Centers for Medicare and Medicaid Services has expanded coverage to include MRA to evaluate renal arteries or pelvic arteries in patients without aortic damage; catheter angiography can be added to MRA when clinically warranted.
Moreover, catheter angiography with embolization can be a most useful nonsurgical adjunct to control the extent of vascular injury.
