Ultrasound-guided hydrodissection for occipital nerve entrapment in a collegiate football player: a case report

This case report presents the successful use of ultrasound-guided hydrodissection in treating prolonged concussion-like symptoms due to occipital nerve entrapment in a 23-year-old Division I collegiate football player. Following a head-to-head collision during a competition, the patient experienced persistent headaches, as well as light and sound sensitivity. Clinical evaluation and ultrasound imaging revealed greater occipital nerve entrapment. A hydrodissection procedure was performed using fluid injection to separate the fascial planes and relieve nerve compression. The treatment was well-tolerated, and the patient experienced immediate and complete symptom resolution within three days. This case demonstrates the potential of ultrasound-guided hydrodissection as a minimally invasive and effective treatment strategy for an occipital nerve entrapment causing concussion like symptoms.
