# Radiologically Evident Oesophageal Dilation in Paediatric Rumination Syndrome With Recurrent Aspiration Pneumonia: A Rare Case Without Achalasia

## TL;DR

A 15-year-old autistic boy with rumination syndrome showed rare oesophageal dilation on CT, unrelated to achalasia, highlighting the role of CT in diagnosing such cases.

## Contribution

This case presents a rare example of structural oesophageal change caused by a behavioral disorder, not achalasia.

## Key findings

- Progressive oesophageal dilation was observed in a patient with rumination syndrome.
- Achalasia was ruled out using imaging techniques.
- CT proved valuable for diagnosis when manometry was not feasible.

## Abstract

A 15‐year‐old autistic boy with rumination syndrome presented with progressive oesophageal dilation on CT. Achalasia was excluded based on imaging. This case illustrates a rare example of structural change likely due to behavioural disorder and highlights the diagnostic value of CT when manometry is unfeasible.

We present a rare example of structural change likely due to behavioural disorder in a 15‐year‐old autistic boy with rumination syndrome who presented with progressive oesophageal dilation on CT. Achalasia was excluded based on imaging.
