Role of ultrasound in evaluation of peripheral nerves.

Lawande AD, Warrier SS, Joshi MS - Indian J Radiol Imaging (2014)

Bottom Line: Ultrasonography (USG) is an excellent cost-effective modality in imaging of peripheral nerves.With the newer high-frequency probes with different footprints which allow high-resolution imaging at relatively superficial location, USG can detect and evaluate traumatic, inflammatory, infective, neoplastic, and compressive pathologies of the peripheral nerves.This article describes the technique for evaluation of nerves by USG as well as the USG appearances of normal and diseased peripheral nerves.

With the newer high-frequency probes with different footprints which allow high-resolution imaging at relatively superficial location, USG can detect and evaluate traumatic, inflammatory, infective, neoplastic, and compressive pathologies of the peripheral nerves. This article describes the technique for evaluation of nerves by USG as well as the USG appearances of normal and diseased peripheral nerves.

Figure 1: Axial USG image of normal nerve showing rounded hypoechoic areas separated by hyperechoic septae, giving a “honeycomb” appearance

Mentions: The normal nerve, in transverse section, reveals small hypoechoic areas separated by hyperechoic septae, giving a “honeycomb-like” appearance.[1] The hypoechoic areas represent nerve fascicles while the echogenic septae represent interfascicular perineurium [Figure 1]. The longitudinal sections also reveal the fascicular architecture, leading to a “bundle of straws” appearance [Figure 2]. The nerve is more echogenic as compared to the muscle which shows hypoechoic muscle fiber bundles with intervening echogenic perimysium. The tendon is more echogenic as compared to the nerve and shows a compact arrangement of echogenic fibrils. On dynamic examination, the nerves show sliding movement over the muscles and tendons. An altered movement or contour deformity during movement of the nerve gives us a clue to diagnose pathology.
