MDCT and MRI of the ampulla of Vater. Part II: non-epithelial neoplasms, benign ampullary disorders, and pitfalls

Abdom Imaging. 2015 Oct;40(8):3292-312. doi: 10.1007/s00261-015-0529-2.


The purpose of this two-part article is to review the cross-sectional imaging features of benign and malignant ampullary conditions with endoscopic and histopathologic correlation and to present the most common pitfalls in the evaluation of the ampulla. In this part, we will review the mesenchymal and secondary neoplasms of the ampulla, a vast array of benign ampullary conditions, causes of bulging papilla, and pitfalls. Familiarity with ampullary pathologic conditions and pitfalls, as well as the use of optimized MDCT and MRI techniques, may improve the diagnostic accuracy of radiologists facing ampullary abnormalities.

Keywords: Ampulla of Vater; Ampullary stenosis; Ampullitis; CT–MRI; Papilla.
