Key result
Coil embolization resolves bilateral internal mammary artery aneurysms in a patient with a COL5A1 variant.
Why the study?
Internal mammary artery aneurysms are rare, potentially life-threatening entities, with true noniatrogenic and nontraumatic cases being uncommonly reported.
Case Report (n=1)
Coil embolization can be a successful treatment for rare bilateral internal mammary artery aneurysms associated with COL5A1 variants and fibromuscular dysplasia.

Coil embolization may be feasible for rare bilateral IMA aneurysms; leaves open the role of COL5A1 variants in management.
Internal mammary artery aneurysms are rare but serious clinical entities. Rupture results in hemothorax and can be life threatening. Most reported cases are pseudoaneurysms secondary to iatrogenic or traumatic causes. Noniatrogenic, nontraumatic, true internal mammary artery aneurysms have most commonly been associated with vasculitides or connective tissue disorders; rare cases have been deemed idiopathic. We describe a rare case of bilateral internal mammary artery aneurysms-successfully treated with coil embolization-in the setting of heterozygosity for a missense variant of unknown significance in the COL5A1 gene and multifocal fibrodysplastic changes on angiography.

Chen et al. (2019) conducted a case report in Bilateral internal mammary artery aneurysms (n=1). Coil embolization was evaluated on Treatment success. Coil embolization successfully treated bilateral internal mammary artery aneurysms in a patient with a COL5A1 missense variant and multifocal fibrodysplastic changes.
