title: Intercostal artery pseudoaneurysm with spontaneous resolution in the setting of an artery of Adamkiewicz.
abstract: We report an extremely unique and previously unreported case of a pseudoaneurysm arising from an intercostal artery that also gave origin to the artery of Adamkiewicz. Due to the potential risk of losing the artery of Adamkiewicz, a conservative approach was indicated. On short interval follow-up imaging, the pseudoaneurysm and associated hematoma spontaneously resolved with preservation of the intercostal artery. We performed a literature review of the natural course of pseudoaneurysm as well as their occurrence in the intercostal arteries.
