# Brown tumours of a rib initially detected by ultrasound: a case report

## TL;DR

This case report describes a rare instance where brown tumours were first detected using ultrasound, highlighting its potential as a diagnostic tool.

## Contribution

The novelty lies in the initial detection of brown tumours via ultrasound, a method rarely used for this purpose.

## Key findings

- Brown tumours were initially identified through ultrasound, a rare occurrence in medical literature.
- The ultrasonographic features of the tumours were detailed, offering insights into their diagnostic potential.
- The paper summarizes clinical and imaging features of brown tumours based on existing literature.

## Abstract

Brown tumours, reactive osteolytic lesions caused by hyperparathyroidism, are usually identified by X-ray, computed tomography, and magnetic resonance imaging, with ultrasonography of brown tumours being only rarely reported in the literature. In this paper, we present a case of brown tumours initially detected during ultrasound examination and subsequently confirmed. We describe the ultrasonographic characteristics in detail and discuss the clinical value of ultrasound as a screening and diagnostic tool. Furthermore, we summarise the clinical characteristics, imaging features, and treatment options of brown tumours based on a thorough analysis of the available literature.
