# Arteriovenous Malformation of the Vallecula Resulting in Recurrent Hemoptysis: A Case Report

## TL;DR

A rare case of a throat arteriovenous malformation causing recurring coughing up of blood is described and successfully treated.

## Contribution

This case report highlights a rare cause of hemoptysis and demonstrates the effectiveness of surgical removal for symptom resolution.

## Key findings

- An AVM in the vallecula was identified as the cause of intermittent hemoptysis.
- Flexible laryngoscopy aided in the diagnosis of the AVM.
- Surgical removal resolved the patient's symptoms.

## Abstract

Arteriovenous malformations (AVMs) of the upper airway in adults are relatively rare and can present with intermittent hemoptysis. Due to the intermittent nature of the bleeding episodes and frequent need for multidisciplinary interventions, diagnosing and treating upper airway AVMs can be challenging.

Here, a case of intermittent hemoptysis due to an AVM of the vallecula is described. It was identified using flexible laryngoscopy and was subsequently surgically removed with resolution of the patient’s symptoms. Overall, hemoptysis in adults has a broad differential and a thorough work up with multidisciplinary involvement should be performed.
