Massive hemoptysis caused by pulmonary artery pseudoaneurysms is uncommon, and endovascular treatment such as coil embolization is the first choice for treating pulmonary artery pseudoaneurysms.

Herein, we describe a case of a pulmonary artery pseudoaneurysm that was successfully treated by endovascular thrombin injection using a microcatheter because of the difficulty in performing a coil embolization due to a short feeding artery.
