Fig. 1. A 59-year-old woman with an ampulla of Vater (AOV) neuroendocrine tumor. The enhanced pancreatic phase abdominal CT images show (a) a 1.5 cm mass (arrow) with avid, homogeneous enhancement at the AOV, (b) a 9.7 cm lobulated enhancing mass with multifocal low attenuating cystic or necrotic change in the right hepatic lobe and (c) a 2.3 cm enlarged lymph node (arrow) with central necrotic change was noted in the left para-aortic area.
