In this report, we present the MRI findings of adenosquamous carcinoma
of the gallbladder, a rare type of gallbladder malignancy. MRI examin
ation not only helped established the diagnosis but also accurately de
picted the extent of involvement of the adjacent liver. The ability to
image in multiple planes was also useful in assessing the anatomic lo
cation of the tumor and in determining that the patient could be treat
ed with surgical resection. (C) Elsevier Science Inc., 1998.
