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.

(A) Longitudinal USG image showing a fusiform predominantly hypoechoic mass lesion along the median nerve in forearm. The nerve can be located eccentrically along the ventral aspect of the mass lesion, suggesting the diagnosis of schwannoma (B) Intraoperative image of the lesion confirming the ultrasound findings (C) Intraoperative image after excision of the mass lesion with preservation of the nerve

Mentions: The most common nerve tumors are nerve sheath tumors which include schwannomas and neurofibromas. It may not always be possible to differentiate between them on USG. They are seen as well-defined ovoid homogeneous hypoechoic lesions with nerve entering and exiting from them. Schwannomas are eccentric along the long axis of nerve, with nerve fascicles seen separately [Figure 6A–C]. Neurofibromas are spindle-shaped with loss of normal fascicular architecture.[6]
