# Ball-Valve Syndrome Secondary to Large Fundic Adenoma

## TL;DR

A rare case of ball-valve syndrome caused by a large stomach tumor is reported, highlighting the need for surgery.

## Contribution

This case report highlights ball-valve syndrome as a rare complication of gastric adenomas in adults.

## Key findings

- A 73-year-old woman presented with intermittent abdominal pain due to a large fundic adenoma causing intussusception.
- The case emphasizes the importance of surgical intervention for managing this rare condition.

## Abstract

Gastroduodenal intussusception is a rare presentation in adults. A mass lesion in the stomach typically acts as a lead point that invaginates into the pylorus and duodenum causing intussusception. In a subset of these cases, episodic symptoms of obstruction occur because of intermittent prolapse of the lesion, termed “ball-valve syndrome.” We present a 73-year-old woman with intermittent abdominal pain and nausea who was discovered to have gastroduodenal intussusception secondary to a large prolapsing fundic adenoma through the pylorus and into the duodenum. The case highlights this rare complication from gastric lesions along with the importance of surgical intervention for definitive management.
