IMAGING FINDINGS OF MUCINOUS TYPE OF CHOLANGIOCELLULAR CARCINOMA

Objective: To demonstrate the imaging findings seen in two cases of mu cinous type of cholangiocellular carcinoma of the liver. Materials and Methods: The CT and MR findings of two patients with pathologically p roven mucinous type of cholangiocellular carcinoma were analyzed. Resu lts: One of them showed calcification, both cases had no enhancing on the arterial dominant phase of dynamic CT, but showed enhancement in t he periphery and internal septations on the equilibrium phase. The int ernal signal intensity was homogenous, and extremely hypo- and hyperin tense on T1- and T2-weighted images, respectively. Conclusion: Imaging findings were unique reflecting the characteristic pathological featu res that cancer cell nests are suspended in a large mucinous lake, and the specific diagnosis was considered to be possible by the integrate d imaging diagnosis.
