Fig. 2B —64-year-old woman with mucinous adenocarcinoma of
gallbladder. On contrast-enhanced CT, mass is clearly visualized as localized
wall thickening with enhancement and some multilocular lesion with rimlike
enhancement (arrow). There also is direct invasion into segment IV of
liver (arrowhead) and metastatic lymphadenopathy (curved
arrow) along bilateral paraaortic area.

Fig. 4A —51-year-old woman with adenosquamous cell carcinoma. On
contrast-enhanced CT scan, huge heterogeneous enhancing mass replaces
gallbladder fossa and directly invades adjacent liver. Mass is composed of
endoluminal (arrow) and exophytic (E) mass with interrupted mucosal
lining.

Fig. 4B —51-year-old woman with adenosquamous cell carcinoma. On axial
T2-weighted MR image (TR/TE, 4/134), endoluminal mass (arrow) shows
low signal intensity, and exophytic mass (E) shows slightly high signal
intensity.

Fig. 4C —51-year-old woman with adenosquamous cell carcinoma. Axial
T1-weighted image (TR/TE, 149/4) shows two components, which are endoluminal
polypoid mass with high signal intensity (arrow) and huge exophytic
mass with low signal intensity (E).
