Omohyoid muscle syndrome: a case report.

Area of Science:

• Anatomy and Physiology
• Medical Diagnostics
• Rare Diseases

Background:

• Omohyoid muscle syndrome is a rare condition.
• First described in China in 1980.
• Characterized by a transient lateral neck mass during swallowing.

Purpose of the Study:

• To present a case of omohyoid muscle syndrome.
• To demonstrate the utility of ultrasound in diagnosing this rare condition.

Main Methods:

• Case report.
• Diagnostic ultrasound imaging of the neck.

Main Results:

• Ultrasound successfully identified features consistent with omohyoid muscle syndrome.
• The transient lateral neck mass was visualized during swallowing.

Conclusions:

• Ultrasound is an effective diagnostic tool for omohyoid muscle syndrome.
• Further research is needed to understand the uncertain pathogenic mechanisms.
