    Neurogenic thoracic outlet syndrome (nTOS) is often underdiagnosed due to nonspecific symptoms and lack of definitive imaging findings.

  • 2

    Ultrasonography revealed significant atrophy of the right subclavius muscle in a patient with unexplained proximal neuropathy.

  • 3

    Ultrasound-guided hydrodissection using 30 mL of 5% dextrose in water led to over 70% improvement in paresthesia after the procedure.

  • 4

    Following six treatment sessions, the patient achieved complete symptom resolution and full motor strength recovery.

    This case highlights the potential of ultrasound-guided hydrodissection as a minimally invasive treatment for refractory nTOS.
