Pseudoaneurysm 

A pseudoaneurysm is usually caused by an injury to the aortic wall leading to blood clot formation outside the outer layer of the aortic wall where there is containment of the blood by the adjacent organs or structures. This is otherwise known as a false aneurysm. In false aneurysms there is no involvement of any of the layers of the aortic wall. In the chronic phase, the fibrous tissues surrounding the blood clot thicken and may resemble the aortic wall. As mentioned, pseudoaneurysms may be associated with aortic ulcerations and traumatic aortic injuries. Patients may present with pain or symptoms related to compression of adjacent organs. Pseudoaneurysms can be diagnosed on CT scan and MRI.
