Core Tip

Core Tip: A traumatic neuroma results from nerve injury after trauma or surgery but rarely occurs in the bile duct. Herein, we present some of the sonographic features of ultrasound and contrast-enhanced ultrasound in a case of a traumatic neuroma. We report this unusual case and review the related literature to improve the diagnosis and differential diagnosis of a traumatic neuroma of the bile duct and related imaging findings.
