## Overview

[edit | edit source]

Ultrasound is beneficial for diagnosis of rhabdomyosarcoma in pelvic and abdominal tumors. Ultrasound findings of rhabdomyosarcoma are in favor of well-defined, irregular mass with low to medium echogenicity.

## Ultrasound

* Ultrasound is beneficial for diagnosis of rhabdomyosarcoma in following cases:[1][2][3]
* Pelvic tumors such as prostate tumors or bladder tumors
* Abdominal tumors for liver evaluation
* Ultrasound findings of rhabdomyosarcoma are:
* Well-defined and irregular mass
* Low to medium echogenicity
