AI Article Synopsis
- Bile duct adenoma (BDA) is a benign liver tumor linked to the intrahepatic bile ducts, and this case highlights its MRI characteristics through a patient's examination.
- A 41-year-old male had a liver lesion discovered during routine checks, which MRI identified as a circular mass with distinct signal properties on T1 and T2-weighted images.
- After surgical resection confirming BDA, the patient showed no signs of recurrence during follow-up, emphasizing the importance of MRI imaging in diagnosing this condition.
Article Abstract
Bile duct adenoma (BDA) is a benign tumor that arises from the epithelium of the intrahepatic bile ducts. Herein, we present a case and discuss the characteristic magnetic resonance imaging (MRI) features of intrahepatic BDA by radiologic-pathologic correlation. A 41-year-old male visited our hospital. He was incidentally shown to have a liver-occupying lesion during a routine medical examination. MRI revealed a 16 mm × 17 mm × 18 mm circular hepatic mass occupying segment 2 of the liver. It showed low signal intensity on T1-weighted images (T1WI) and high signal intensity on T2-weighted images (T2WI). Diffusion-weighted imaging (DWI) MRI showed a ring of high intensity. Gadolinium ethoxybenzyl diethylenetriaminepentaacetic (Gd-DTPA) dynamic enhanced scanning showed a prolonged "ring enhancement" pattern. It showed a ring of high intensity in the hepatobiliary specific period and low signal peripheral and central of the tumor. The pathology result of the surgical resection showed a diagnosis of intrahepatic BDA. Postoperatively, the patient is currently under outpatient observation for seven months with no apparent recurrence. Intrahepatic BDA can be characterized as a small circular lesion located in the liver. MRI and pathologic features are well characterized in this tumor. MRI enhancement plays an important role in the diagnosis and evaluation of BDA.

A 70-year-old man was incidentally diagnosed with a single hepatic mass lesion in his right hepatic lobe during a computed tomography scan. The lesion exhibited consistent enhancement with contrast agents on computed tomography (CT), magnetic resonance imaging (MRI), and hepatic arterial angiography. While a definitive diagnosis could not be made preoperatively, the lesion was surgically resected due to its slight enlargement over two months, suggesting a potential malignancy.

Bile duct adenomas (BDAs) are rare benign tumors that can arise in the intra-hepatic or extra-hepatic biliary tree. We present a case of a 46-year-old female who presented with symptoms suggestive of choledocholithiasis. Direct cholangioscopy identified a 15 mm polypoid lesion in the common hepatic duct (CHD).

Intrahepatic Cholangiocarcinoma Coexisting With Multiple Bile Duct Adenoma Treated as Liver Metastasis from a Pancreatic Neuroendocrine Tumor.

Department of Surgery, Yamaga City Medical Center, Kumamoto, Japan;
Background: Bile duct adenomas (BDA) may be precursor lesions of small duct-type, including mass-forming type intrahepatic cholangiocarcinoma (ICC).
Case Report: A 68-year-old woman was transferred to our facility for the treatment of a liver tumor, possibly metastasized from a pancreatic neuroendocrine tumor. Finally, two liver tumors were resected and histopathologically diagnosed as "BDA" and "ICC with a BDA-like component".
Clinical Utility of Bile Duct Axis Deviation for Differential Diagnosis Between Pancreatic Head Cancer and Bile Duct Cancer.

Department of Surgery, Toyonaka Municipal Hospital, Osaka, Japan.
Backgrounds: Differential diagnosis between pancreatic head cancer (PHC) and intrapancreatic bile duct cancer (BDC) is important, but no clinical standard has been established. Here we examine the diagnostic utility of bile duct axis deviation and other clinical factors for this differential diagnosis.
Methods: This study enrolled patients who underwent pancreaticoduodenectomy for PHC or BDC at our center between 2009 and 2016.
