# A Unique Case of Gallstone Ileus in a Patient With Crohn's Disease: Stone Impaction in an Ileal Adenocarcinoma

## TL;DR

A rare case of gallstone ileus in a Crohn's disease patient is linked to an ileal adenocarcinoma.

## Contribution

Highlights the importance of considering malignancy in Crohn's patients with new intestinal strictures.

## Key findings

- Gallstone ileus occurred secondary to an ileal adenocarcinoma in a Crohn's disease patient.
- Crohn's disease increases the risk of both gallstones and gastrointestinal malignancies.
- New strictures in Crohn's patients should prompt evaluation for underlying malignancy.

## Abstract

Gallstone ileus represents an uncommon etiology of mechanical intestinal obstruction. Individuals with Crohn's disease are predisposed to both increased gallstone formation and a heightened risk of gastrointestinal malignancy. This case highlights the necessity of excluding malignancy when evaluating newly developed strictures in this patient population.
