Abstract

We herein report the histopathology of a rare case of an idiopathic internal mammary artery aneurysm in a 61-year-old asymptomatic woman. Chest radiography during an annual medical check-up incidentally revealed the aneurysm, which was initially mistaken for a mediastinal tumor. Given that a rupture of the aneurysm could have been life-threatening, it was removed surgically, and found to possess a paper-thin arterial wall with cystic medial degeneration.
