Aberrant left subclavian artery aneurysm with esophago-arterial fistula. CT demonstration.
Esophago-arterial fistula is a rare but life-threatening complication of an aberrant subclavian artery aneurysm. We report the computed tomography appearance of such a fistula. The characteristic location, presence of rim calcification, and interspersed air and thrombus allowed for prompt preoperative diagnosis and surgery.
