  • Title: MRI visualization of the aortic nipple.
    Author: Medrea M, Meydam K, Schmitt WG.
    Journal: Cardiovasc Intervent Radiol; 1988; 11(1):29-31. PubMed ID: 3130995.
    Abstract:
    The aortic nipple, a small "pseudotumor" adjacent to the aortic arch, is the left superior intercostal vein. In our series of 40 patients it was demonstrated in six; all had a right upper thoracic mass and four had a superior vena caval syndrome. Coronal magnetic resonance images (MRI) of the thorax were superior to all other imaging methods in demonstrating the nipple. It is concluded that in patients with masses in the right upper chest, coronal MR chest examinations are valuable in demonstrating an aortic nipple, a sign of impending present superior vena caval or innominate vein obstruction.
