Idiopathic internal mammary artery aneurysm in the setting of aberrant right subclavian artery

摘要

Aneurysms of the internal mammary artery are extremely rare. Immediate treatment is necessary because of the high risk of rupture that can be life-threatening. Here we describe a case of idiopathic internal mammary artery aneurysm in a 54-year-old woman in the setting of aberrant right subclavian artery. The aneurysm was successfully treated with coil embolization without complications.
