Intercostal artery aneurysm associated with coarctation of the aorta: specific finding on MR imaging.
Aneurysm formation has been described in association with aortic coarctation in approximately 10% of patients. The incidence increases with age and reaches 42% in patients over 40 years of age. To our knowledge, only six radiologic reports have described aortic coarctation in association with an intercostal artery aneurysm and none of these reports has described an intercostal artery entering the aneurysm. We present a case in which MR imaging helped identify this unusual abnormality.
