Figure 8a. Duodenal lymphoma in a 63-year-old woman. (a) Follow-up CT scan demonstrates a large, lobulated mass of the duodenum (arrows) that obscures normal tissue planes. The second portion of the duodenum contains a biliary stent (arrowhead). (b) VR image demonstrates a large, lobulated lymphoma (arrowheads) that infiltrates the pancreas and obscures known tissue boundaries. The biliary stent (long arrow) is seen in the second portion of the duodenum (short arrow).
