# Bronchial Dieulafoy: Diagnostic Utility of Endobronchial Ultrasound

## TL;DR

This paper discusses how endobronchial ultrasound helps diagnose bronchial Dieulafoy, a condition that can look like a tumor and cause dangerous bleeding if biopsied.

## Contribution

The paper demonstrates the novel use of EBUS in safely diagnosing bronchial Dieulafoy and avoiding risky procedures.

## Key findings

- EBUS confirmed the vascular nature of a bronchial Dieulafoy lesion.
- EBUS can prevent life-threatening complications from unnecessary biopsies.
- Bronchial Dieulafoy can mimic endobronchial tumors on bronchoscopy.

## Abstract

We report a case of bronchial Dieulafoy presenting with haemoptysis, initially resembling an endobronchial tumour on bronchoscopy. This case highlights the critical role of EBUS in the assessment of suspicious endobronchial lesions and in preventing potentially life‐threatening complications from inadvertent biopsy.

Bronchial Dieulafoy can mimic an endobronchial tumour and pose a risk of life‐threatening bleeding if biopsied. Endobronchial ultrasound (EBUS) confirmed the vascular nature of the lesion, guiding safe and effective management.
