“…24,25 The prevalence of hepatic mucinous cystic neoplasm in segment IV may support an implant origin because hamartomatous lesions commonly develop in segment IV. 26,27 The expression of oestrogen receptor or PgR in ovarianlike stroma also supports a putative role for female hormones in the tumorigenesis. 28 In conclusion, hepatic mucinous cystic neoplasms and biliary intraductal papillary neoplasms have different clinicopathological characteristics as evidenced by differences in the age and gender of patients, macroscopic appearance, immunophenotypes, and grades of malignancy.…”

Mucinous cystic neoplasm of the liver has been a controversial entity, in particular, regarding differentiation from intraductal papillary neoplasm of the bile duct. In this study, we compared the characteristics of hepatic mucinous cystic neoplasms with ovarian-like stroma (n ¼ 29) to those of cyst-forming intraductal papillary neoplasms of the bile duct (n ¼ 12). Radiological or macroscopic appearance, histological grade of malignancy, and postoperative clinical course were recorded. Immunohistochemistry for biliary or gastrointestinal markers was performed to characterize cell phenotypes. The patients with hepatic mucinous cystic neoplasm were all female and ranged in age from 21 to 67 years, which was significantly younger than that in the patients with biliary intraductal papillary neoplasm. Eighteen mucinous cystic neoplasms (76%) were located in the left lobe, with 13 (54%) in segment IV. Mucinous cystic neoplasms were significantly larger than intraductal papillary neoplasms (median diameter: 110 vs 50 mm, P ¼ 0.008). In contrast to intraductal papillary neoplasms that were all histologically malignant, 26 mucinous cystic neoplasms (90%) were adenomas, 2 (7%) were borderline malignant, and 1 (3%) was a carcinoma in situ. Benign mucinous cystadenomas had the pure biliary immunophenotype, whereas gastrointestinal markers including cytokeratin 20 and mucin core proteins 2, 5AC, and 6 were more frequently expressed in borderline or malignant mucinous cystic neoplasms and biliary intraductal papillary neoplasms. There was no mortality in the patients with mucinous cystic neoplasm, whereas one patient with intraductal papillary neoplasm died of cancer. In conclusion, hepatic mucinous cystic neoplasms and biliary intraductal papillary neoplasms have different clinicopathological characteristics as evidenced by differences in the age and gender of patients, macroscopic appearance, immunophenotypes, and grades of malignancy.

“…Previous reports indicate that the ciliated foregut cysts in the liver are not enhanced after the injection of contrast material (8). In another case, a study of the gallbladder found that no enhancement was seen for the same finding of a contrast-enhanced CT (5).…”

“…Radiologically, CHFC tends to be hypoechoic on ultrasound, and iso-to hyperattenuating on unenhanced CT and does not contrast-enhance [13,14]. On MRI imaging, cysts have been reported to be hyper-, hypo-, and isodense on T1 imaging and may be markedly hyperintense or isointense on T2 imaging [15].…”

Ciliated hepatic foregut cysts (CHFC) are rare, typically benign, lesions whose incidence has been increasing recently. Despite this increase in incidence, they remain rare and several key characteristics remain poorly understood, including the range of presentation and the risk of malignant conversion. To better understand CHFC, an extensive review of the international literature was performed. Characteristics including size, location, contents, presenting symptoms, and risk of malignancy were analyzed. In addition, an illustrative case is presented to highlight a potential pitfall in diagnosis: Although the presentation is thought to be typically painless or vaguely painful, these lesions may also present with hemorrhage and sudden severe abdominal pain. Importantly, although malignant degeneration is uncommon, analysis revealed that malignancy is significantly associated with size, which was significantly larger (median 10 cm) in malignant CHFC compared with the typical benign CHFC (3 cm) (p < 0.01). Large or symptomatic cysts, or small asymptomatic cysts that are atypical, should be resected.
