“…To our knowledge, this is the first detailed comprehensive review of the imaging characteristics of BAF in the published literature. Lee et al [ 17 ] simply summarized the MRI findings of 8 patients with BAF, but not the radiologic features of other imaging modalities or the enhancement patterns of lesions.…”

Background Biliary adenofibroma (BAF) is a rare primary hepatic tumor with the potential risk of malignant transformation. Given the extreme rarity of the disease, the imaging features of BAF are unclear. We presented a case of malignant BAF and conducted a systematic literature review. We highlighted the key imaging features in the diagnosis and aggressiveness assessment of BAF, as well as the role of various imaging modalities in evaluating BAF. Case presentation We reported a 64-year-old woman with a 5-months history of pain in the right upper quadrant abdomen. US of the liver showed a hypoechoic subcapsular nodule. CT scan revealed a subcapsular solid-cystic mass in segment V of the liver. The mass showed a marked enhancement in the arterial phase followed by wash-out in the venous phase. The patient underwent partial resection of liver’s right lobe. The mass was diagnosed as BAF with malignant transformation by postoperative pathology. Conclusions CT and MRI are helpful in recognizing and characterizing BAF. The imaging features of BAF include a solitary, large solid-cystic mass with a well-defined margin, lobulated shape, and internal septa; subcapsular location; no intrahepatic bile duct communication; the presence of von Meyenberg complexes in background liver. The enhancement patterns may have the potential to assess the aggressiveness of BAF, and that marked enhancement in the arterial phase followed by wash-out in the venous phase is suggestive of malignant BAF.

“…Characteristic MRI-findings of biliary adenofibroma have previously been suggested to be a well-circumscribed multicystic tumor with septal enhancement and no intrahepatic bile duct communication, based on a report of two cases and a review of MRI features reported in the literature [8]. Differential diagnoses for biliary adenofibroma include cystic neoplasms such as intraductal papillary neoplasms of the bile duct (IPNB) and mucinous cystic neoplasm of the liver (MCN) [8].…”

“…Liver function indices were within normal limits. One patient had a history of hepatitis B[ 21 ], but the hepatitis status was not mentioned in the remaining patients. The location of the lesion was the left lobe in 11 patients and the right lobe in 13 patients (the specific location of the liver lesion was not mentioned in the remaining patient).…”

“…There was no significant change in the signal of the lesion in the in-phase and out-phase sequence. In previous cases, the bile duct epithelial components of the lesions had no secretory function, but some lesions showed a tendency to enlarge and develop cystic components during the follow-up period[ 21 ]. The diameter of the solid lesions in three cases[ 8 , 10 , 20 ] and the solid lesions in the present case were smaller (4.08 ± 1.16 cm) than the mean diameter of the cystic and solid lesions (7.00 ± 3.03 cm).…”

“…Pathological examination revealed that the fibrous tissue matrix of the tumor showed the histological pattern of a partially cystic bile duct. The bile pigment component in the tumor duct indicated direct continuity between the lesion and the biliary system, although postoperative pathology showed that the lesion was not clearly connected with the bile duct[ 6 , 21 ]. Primovist is a hepatobiliary-specific contrast agent that can show the biliary system in the hepatobiliary phase.…”

BACKGROUND Biliary adenofibroma (BF) is a rare benign epithelial tumor with the possibility of malignant transformation. Its main pathological feature is a well-defined cystic or honeycomb mass. BF has no specific clinical manifestations or laboratory and imaging findings; thus, it is easily misdiagnosed before surgery. This report describes a case in which biliary cystadenoma was misdiagnosed preoperatively and BF was diagnosed postoperatively. The imaging features, particularly the magnetic resonance imaging (MRI) features, were analyzed and summarized. CASE SUMMARY A 68-year-old Chinese man was admitted to our hospital with a 2-mo history of abdominal discomfort. Following admission to our hospital, laboratory examinations showed normal tumor marker concentrations and liver function. Hepatocellular carcinoma was considered after contrast-enhanced ultrasound examination. MRI suggested the possibility of cystadenoma of the bile duct. However, postoperative pathological examination confirmed the diagnosis of BF. No local recurrence was found 1 mo after surgery. CONCLUSION Our objective is to highlight the imaging diagnostic value of BF, especially on an MRI enhanced scan with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid.
