Histologically, cystadenocarcinomas are usually lined by ductal-type adenocarcinoma cells and demonstrate intracystic
papillae that can be exuberant (Figure 9, A through C).
Abdominal computed tomography revealed a distended, wide, double-border gallbladder with intracystic
extravasation, whereas the biliary tract appeared normal (Figure 1).
(6) Papillary was dropped from the name in the 2005 WHO classification, as the intracystic
papillary projections were not always a prominent feature.

For recurrent cystic hygroma, intravenous cyclophosphamide and intracystic

(3) Imaging findings that support a diagnosis of malignancy are nodular wall thickness and thickening of the mass, intracystic

MCN with an associated invasive carcinoma manifests as a large unilocular or septated cystic lesion with intracystic

The cystectomy was successfully performed without rupture and the piece was sent to the parasitology laboratory with evidence of proliferative membrane (macroscopically) and alive scolex in the intracystic
fluid (microscopically) (Figure 4).
