# Elbow calcific tendinosis initially detected by ultrasonography: a case report

## TL;DR

A case report shows ultrasonography can detect elbow calcific tendinosis, even when a lipoma is present, offering both diagnostic and therapeutic benefits.

## Contribution

Demonstrates the utility of ultrasonography in diagnosing calcific tendinosis alongside potential interfering conditions like lipoma.

## Key findings

- Ultrasonography revealed a thickened, heterogeneously hypoechoic pronator teres tendon consistent with calcific tendinosis.
- A subcutaneous lipoma was also detected, highlighting the importance of accurate imaging for differential diagnosis.
- Ultrasonography's real-time nature supports both diagnosis and treatment of calcific tendinosis.

## Abstract

Calcific tendinosis is a common condition caused by the deposition of hydroxyapatite crystals within the tendons that can impact any tendinous insertion. In this situation, ultrasound (US) may be a viable imaging modality in addition to radiography.

A 56-year-old Iranian male presented with left elbow pain. US evaluation at the lump site revealed a subcutaneous lipoma. Ultrasonography showed a thickened and diffusely heterogeneously hypoechoic pronator teres tendon. These characteristics were consistent with the diagnosis of calcific tendinosis.

Radiography is the most common and practical imaging modality for calcific tendinosis diagnosis. Despite this, the real-time nature of ultrasonography makes it both diagnostic and therapeutic in this condition. Other conditions, such as lipoma, may interfere with the proper diagnosis of calcific tendinosis.
