# Resection of Biliary Cystadenoma in a Pregnant Woman: A Case Report With Five Years of Follow-Up

## TL;DR

A pregnant woman successfully underwent surgery to remove a rare liver tumor, with no recurrence after five years.

## Contribution

This case report highlights successful resection of BCA during pregnancy with long-term follow-up.

## Key findings

- Complete resection of a mucinous hepatobiliary cystadenoma was achieved in a pregnant patient.
- Five-year follow-up confirmed no tumor recurrence.
- Surgical intervention is recommended for BCAs to prevent potential malignancy.

## Abstract

Biliary cystadenomas (BCAs), rare cystic tumors occurring in the biliary system, account for fewer than 5% of cystic lesions in the liver. This case details successful resection in a 29-year-old pregnant woman at seven weeks gestation. Urgent left hemihepatectomy and cholecystectomy removed a mucinous hepatobiliary cystadenoma. Postoperatively, a healthy newborn was delivered by cesarean section. Five-year follow-up showed no recurrence. BCAs present diagnostic challenges due to nonspecific symptoms, and surgical intervention, preferably complete resection, is recommended for potential malignancy, after weighing benefits against complications in critical hepatic vessel lesions.
