Purpose or Case Report: Muscle hernias occur when a muscle protrudes through a fascial defect into the subcutaneous fat, hence presenting as a subcutaneous palpable mass. While the palpable abnormality is usually asymptomatic, it can also present with pain. Muscles hernias occur most often in adolescents and young adults and might be due to sporting activities, trauma, or overlying fascia weakness.

Because of its dynamic real-time imaging capabilities, ultrasound is best suited for the evaluation of these lesions. Moreover, a definitive diagnosis can be reached with ultrasound hence avoding additional time and expenses while promptly providing reassurance to the patients and families. US has excellent sensitivity and specificity for the identification of muscles hernias. However, baseline knowledge of this disease as well as close attention to technique are needed to reliably reach the proper diagnosis. Our educational poster will:
1. Summarize proper US equipment, technique and protocol for diagnosing muscle hernia
2. Discuss advantages and benefits of US over other imaging modalities
3. Illustrate the sonographic findings of muscles hernias


Methods & Materials: Pictorial review of US findings of muscle hernias including grayscale and color Doppler.
Results: The spectrum of normal and abnormal deep soft tissues scanning are presented. Abnormal findings are presented using illustrative cases.

Conclusions: Ultrasound is a powerful tool that is particularly well suited for the evaluation of suspected or unsuspected muscle hernias. This educational exhibit provides a practical guide to identify and diagnose muscle hernias.
