Brachial plexus neuropathy can have a high morbidity by seriously affecting the motor function and sensation of upper limbs with loss of activities of daily living. The use of computed tomography myelogram and/or magnetic resonance imaging (MRI) assessing brachial plexus offers valuable details including the location, morphology, and severity of preganglionic and postganglionic injuries during the preoperative period. High-field-strength MRI with specific coil and specialized MRI sequences might be not available in every emergency setting and is time-consuming. Point-of-care ultrasonography (POCUS) comes in handy and offers good image resolution of muscles and nerves that makes early detection of neuromuscular injury possible. Here, we present a case report of BPI that POCUS provides indirect evidence of cervical root injury and expedite time to MRI.3enjournal article
