# Hepatic Duct Adenoma Identified Using Direct Cholangioscopy

## TL;DR

A rare bile duct tumor was diagnosed in a 46-year-old woman using direct cholangioscopy, emphasizing its value in identifying such lesions.

## Contribution

Demonstrates the utility of direct cholangioscopy in diagnosing bile duct adenomas.

## Key findings

- Direct cholangioscopy identified a 15 mm polypoid lesion in the common hepatic duct.
- Biopsy confirmed the lesion as a bile duct adenoma.

## Abstract

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). Biopsy revealed a BDA. We present this case to highlight the role of direct cholangioscopy in the diagnosis and management of BDAs.
