The management of patients with CAAs is challenging due to poorly understood mechanism, variable presentation, and lack of clear-cut societal recommendations. Though conservative management is preferred in asymptomatic patients, massive size or interval growth may make intervention necessary.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>We describe a case of successful coil embolization of a giant coronary aneurysm in an elderly 84-year-old male. Patient, who presented for a follow-up computed tomography angiography to evaluate a previously repaired abdominal aortic aneurysm 2 years back, was found to have interval growth of right coronary artery aneurysm from 4\u2009cm in diameter to 7 \u00d7 8\u2009cm in its greatest dimensions. The rationale for treatment was to prevent sudden death from continued growth and eventual rupture of aneurysm in addition to potential risk of thromboembolism and compression of adjacent structures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>This case demonstrates the safe and
