Ultrasound diagnosis of traumatic neuroma in peripheral nerve / 中华超声影像学杂志

ABSTRACT

Objective To analyze sonographic imagings of traumatic neuromas of peripheral nerves,and to investigate the applied values of uhrasonography in the traumatic neuroma of peripheral nerve. Methods The sonographic imagings of 38 patients who had evidences of traumatic neuromas in peripheral nerves were retrospectively reviewed by the last diagnostic results of operations. Results Among 38 cases, 2 incomplete traumatic neuromas were not detected, and 1 incomplete traumatic neuroma was misdiagnosised as neurilemoma by ultrasonography. The coincidence of uitrasonography in incomplete traumatic neuroma and complete severed neuroma was 82.4% and 100%. With regard to the echogenicity of 38 traumatic neuromas of peripheral nerves, the sonographic characteristics of neuromas were all hypoechoic. Thirty-three neuromas appearanced like shuttles and 5 neuromas appearaneed like humps. Conclusions The traumatic neuroma has distinctive ultrasonic appearance. Ultrasonography is useful to direct the diagnosis and treatment of traumatic neuroma.
