Abstract
To demonstrate the imaging findings seen in two cases of mucinous type of cholangiocellular carcinoma of the liver. The CT and MR findings of two patients with pathologically proven mucinous type of cholangiocellular carcinoma were analyzed. One of them showed calcification, both cases had no enhancing on the arterial dominant phase of dynamic CT, but showed enhancement in the periphery and internal septations on the equilibrium phase. The internal signal intensity was homogenous, and extremely hypo- and hyperintense on T1- and T2-weighted images, respectively. Imaging findings were unique reflecting the characteristic pathological features that cancer cell nests are suspended in a large mucinous lake, and the specific diagnosis was considered to be possible by the integrated imaging diagnosis.
