Figure 17.

A 32-year-old female with lymph node metastasis from mucinous adenocarcinoma of the transverse colon (not shown). A: The portal venous phase of an axial computed tomography shows a low density mass (arrow) adjacent to the pancreatic head (asterisk); B: Axial magnetic resonance cholangiopancreatography shows the mass to be high intensity, mimicking microcystic serous cystic neoplasm (SCN). However, the presence of primary tumor and the lesion location (transverse mesocolon) are suggestive of lymph node metastasis rather than microcystic SCN.
