# A Rare Choledochal Cyst in a Child With Abdominal Pain

## TL;DR

This paper describes a rare case of a choledochal cyst in a child, highlighting the importance of early detection to prevent future cancer.

## Contribution

The novelty lies in presenting a case emphasizing early diagnosis of choledochal cysts in children to avoid malignant transformation.

## Key findings

- Choledochal cysts can present with nonspecific symptoms and are often diagnosed late.
- Early detection in children may prevent future malignancy like cholangiocarcinoma.
- The case illustrates the importance of considering rare biliary anomalies in pediatric abdominal pain.

## Abstract

Choledochal cysts are rare anatomical anomalies of the biliary tree. These lesions possess a risk for future development of catastrophic malignancy in the form of cholangiocarcinoma if left unaddressed, which is associated with a high mortality rate in cases of malignant transformation. The presenting symptoms of choledochal cysts are often nonspecific. The age of the initial onset of symptoms can vary, and some patients with choledochal cysts do not receive a diagnosis until reaching adulthood. Here, we present a case that serves as an example of early detection of this rare clinical finding for potentially devastating malignancy in a child who presented with nonspecific symptoms.
