MRI
Irregular wall thickening of the gallbladder with a heterogeneous enhancing gallbladder fundus mass lesion is noted that measures about 46*50*58 mm in its maximum diameters with an ill definition and infiltration of gallbladder fossa at the fundal region associated with multiple delayed enhancing liver metastatic mass lesions at adjacent segments (IVa and V) up to 20*27 mm.
Porta hepatis metastatic lymphadenopathy up to 14*23 mm also is seen.
Regarding above imaging findings, gallbladder carcinoma stage IIIB is the primary differential diagnosis.
