Dissecting Thoracic Aneurysm in Takayasu Arteritis With Concomitant Tuberculosis.

We present a case of dissecting aneurysm of ascending aorta in a 15-year-old patient secondary to Takayasu arteritis with concomitant tuberculosis, with an emphasis on multimodality imaging findings and to illustrate preoperative and postoperative medical management. Antituberculosis therapy, high-dose corticosteroids, antiplatelet therapy, and β-blockers were administrated during the initial active phase. The patient presented with acute chest pain 3 months after medical therapy initiation. We performed an ascending aorta and aortic arch replacement with branched Dacron grafts. Only a handful of similar, but not identical, cases of Takayasu arteritis with concomitant tuberculosis leading to aortic dissection have been described previously.
