“…4,8 Fernández-Carrión et al observed no metabolic increase on PET/CT. 7 In our case, 18 F-FDG PET/CT showed increased uptake in the tumor, possibly reflecting xanthogranulomatous inflammation. Multicystic biliary hamartoma pathologically presents as a multilocular cystic lesion.…”

A 70-year-old man with a liver tumor was pathologically diagnosed with multicystic biliary hamartoma with xanthogranulomatous inflammation. Plain CT revealed an inhomogeneous low-density liver tumor, measuring 43 × 35 mm. Dynamic contrast-enhanced CT revealed a cyst, measuring approximately 15 mm, with a ring-shaped enhancement, within the tumor. There was delayed enhancement on the outer portion of the tumor. Mild peripheral bile duct dilation was also observed. 18F-FDG PET/CT showed focal high uptake with an SUVmax of 5.2 near the cyst. The findings of this case mimicked that of intrahepatic cholangiocellular carcinoma.

“…Bile duct hamartoma in the liver (LBDH), also known as von Mayenburg complex (VMC) and polycystic bile duct hamartoma, is a benign malformation of the intrahepatic bile duct associated with bile duct plate defects ( 1 , 2 ). The clinical symptoms and signs of disease in patients are often atypical, so these tumours are usually incidentally found during physical examination, exploratory laparotomy or autopsy.…”

Bile duct hamartoma in the liver (LBDH) is relatively rare among the hepatic space-occupying lesions that occur in adults, and the malignant transformation of LBDH is even rarer. In the present case report, a 63-year-old male was found to have two space-occupying lesions in the right lobe of the liver upon ultrasound examination. Enhanced computed tomography (CT) suggested benign hepatic haemangioma, and contrast-enhanced ultrasonography (CEUS) suggested well-differentiated hepatocellular carcinoma. The final pathology results revealed the malignant transformation of LBDH into well-differentiated intrahepatic cholangiocarcinoma. Improved recognition of this type of rare disease can be obtained by radiographic analysis of this case. These findings contribute to a better understanding of the enhanced development pattern of this disease on contrast-enhanced CT, as well as on CEUS.

“…Multicystic biliary hamartoma (MCBH) is an extremely rare benign liver lesion which was initially de ned by Zen et al in 2006. [1] Since then, only fteen cases have been reported as MCBH in the English literature [1][2][3][4][5][6][7][8][9][10][11]. The typical characteristics of MCBH are a gross, well-circumscribed, multicystic honeycomb appearance and histological ndings of cystic or ductal structures composed of ductal epithelium, with various amounts of peribiliary (periductal) glands and brous connective tissue within the lesion [1.2].…”

Background Multicystic biliary hamartoma (MCBH) is an extremely rare benign liver lesion characterized by a gross well-circumscribed multicystic honeycomb appearance. This report presents a MCBH case with a marked peribiliary gland component which showed unusual histology. Case presentation: A 63-year-old Japanese male was admitted to our hospital for a detailed examination of a hepatic cystic lesion, which was originally detected 14 years ago and had slowly enlarged. A preoperative imaging study revealed a well-demarcated multicystic lesion without communication to the biliary tracts. The possible clinical diagnoses were mucinous cystic neoplasm (MCN) or MCBH. The lesion was successfully resected by purely laparoscopic right anterior sectionectomy considering the malignant potential of the lesion and hepatic functional reserve of the patient. The cut surfaces of resected specimens grossly exhibited a well-circumscribed multicystic lesion with a thick septum. Histologically, the cyst wall was covered by cuboidal epithelial cells resembling epithelium of the bile duct while abundant small ducts, which morphologically resembled peribiliary glands, were observed among the fibrous stroma of the thick septum. Although possible pathological diagnosis varied, including intrahepatic cholangiocarcinoma, intraductal papillary neoplasm of the bile duct, biliary adenofibroma, MCN and MCBH, the lesion was finally diagnosed as MCBH with a marked peribiliary gland component. Conclusions MCBH can contain abundant peribiliary glands in the fibrous stroma. A pathologist should be careful not to diagnose such peribiliary glands in MCBH as neoplastic glands.
