# Fibromuscular dysplasia of the brachial artery diagnosis by Doppler ultrasound: a case report

## TL;DR

This case report describes a rare instance of fibromuscular dysplasia in the brachial artery of an asymptomatic patient, diagnosed using Doppler ultrasound.

## Contribution

The paper presents a rare case of FMD in the brachial artery, highlighting its detection via Doppler ultrasound in an asymptomatic individual.

## Key findings

- Fibromuscular dysplasia was identified in the brachial artery using Doppler ultrasound.
- The patient was asymptomatic, making the case particularly unusual.
- The condition is typically found in renal arteries and not in limb arteries.

## Abstract

Fibromuscular dysplasia (FMD) is a disease of non-inflammatory vascular origin that occurs in medium-sized arteries. Its cause is still unknown. The disease mostly affects middle-aged Caucasian women and, in most cases, involves the renal artery. Disease involvement in the arteries of the upper and lower limbs is rare. We report a case of fibromuscular dysplasia of the medial layer of the brachial artery in an asymptomatic patient using Doppler Ultrasound.

A displasia fibromuscular é uma doença vascular não inflamatória que acomete artérias de médio calibre e cuja etiologia permanece desconhecida. A doença predomina em mulheres caucasianas de meia-idade, afetando majoritariamente a artéria renal. O envolvimento das artérias dos membros superiores e inferiores é raro. Relatamos um caso raro de displasia fibromuscular da camada média da artéria braquial em uma paciente assintomática, identificada por meio de ultrassom Doppler.
