Abstract:
Angiosarcomas are rare vascular connective tissue tumors originating from the tunica intima, media, or adventitia and may arise in large vessels. Here two cases of primary angiosarcoma of the aorta are described that highlight initial manifestations and unique complications from diffuse arterial tumor emboli, which led to delayed cancer diagnosis. In patients with aortic lesions, imaging characteristics must be thoughtfully reconciled with clinical scenarios, particularly in patients with no additional evidence of atherosclerosis or vasculitis.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
