# Severe Diaphragmatic Eventration Presenting With Recurrent Syncope: A Rare Case Report

## TL;DR

A rare case of diaphragmatic eventration causing recurrent fainting is reported, highlighting the importance of thorough clinical evaluation and imaging for diagnosis.

## Contribution

This case report presents a rare presentation of diaphragmatic eventration with syncope, adding to the limited clinical literature on the condition.

## Key findings

- Diaphragmatic eventration was diagnosed through contrast-enhanced CT scans showing an elevated left hemidiaphragm.
- The condition was associated with upward displacement of abdominal organs into the thoracic cavity.
- Symptomatic syncope was a rare presenting feature of this anatomical abnormality.

## Abstract

Diaphragmatic eventration is a rare condition with an estimated incidence of less than 0.05% and is often discovered incidentally. Very rarely, symptomatic patients may present with syncope. Meticulous clinical assessment and appropriate imaging studies are crucial for unraveling the diagnosis.
