# Foreign Body Ingestion Ending Up in Late-Presenting Morgagni Hernia Diagnosis: A Case Report

## TL;DR

A two-year-old boy with a history of foreign body ingestion was later diagnosed with a rare Morgagni hernia, which was successfully treated with surgery.

## Contribution

This case highlights the incidental diagnosis of Morgagni hernia during evaluation for foreign body ingestion in a pediatric patient.

## Key findings

- Morgagni hernia was diagnosed in a two-year-old boy with a history of foreign body ingestion and abdominal pain.
- Diagnostic imaging confirmed the diaphragmatic defect, and laparoscopic repair led to a successful recovery.
- Late-presenting Morgagni hernia can be incidentally identified through imaging performed for unrelated reasons.

## Abstract

Morgagni hernia (MH), also known as a retrosternal or parasternal hernia, is a rare type of congenital diaphragmatic hernia (CDH) characterized by a defect in the anterior diaphragm. Patients with late-diagnosed MH typically present with vague gastrointestinal or respiratory symptoms. In some instances, MH is incidentally identified through chest X-rays performed for other reasons, such as foreign body ingestion, as illustrated in our presented case. We present a case of a delayed congenital diaphragmatic hernia of the Morgagni type in a two-year-old boy with a history of foreign body ingestion and severe abdominal pain. Diagnostic imaging, including chest radiograph and computed tomography (CT) scan, confirmed the diaphragmatic defect. Surgical repair, performed laparoscopically, resulted in an uncomplicated postoperative course and a favorable long-term outcome.
