Oat Cell Carcinoma Presenting as a Pseudoaneurysm

Ascending Aortic B-Cell Lymphoma Masquerading as Intramural Hematoma: A Case Report

“…Previous case reports of tumors mimicking aortic dissections or aneurysms have been reported [12][13][14], although most have been prior to the availability of high-resolution CT or MRI. In cases with unusual presenting symptoms or an unreliable history confirmatory imaging is critical to establishing the correct diagnosis and avoiding unnecessary surgery.…”

Pulmonary Large Cell Carcinoma Mimicking an Infected Thoracoabdominal Aortic Aneurysm

“…2 Furthermore, the patient had repeated attacks of thromboembolism, probably because tumor cells were migrating into the mural thrombus in the aorta. This pattern of the tumor presentation is extremely rare, 3 and symptoms and images obtained before surgery led to the diagnosis of an infected aortic aneurysm. An infected aortic aneurysm is an uncommon disease 2 ; however, the imaging characteristics overlap with those of tumors, such as a rapidly expanding mass with heterogeneous enhancement.…”
