From: Imaging in the diagnosis of ulnar nerve pathologies—a neoteric approach
a Hypoechoic ulnar nerve (between white stars and crossheads) is noted in a case with glass cut injury to the wrist. At the site of injury, there is formation of neuroma in continuity (yellow arrow) characterised by thickened, hypoechoic focal area with loss of fascicular architecture. Also noted is soft tissue swelling (red arrow). Yellow arrowhead marks the ulnar artery. b T1- and T2-weighted images show the ulnar nerve neuroma which is hypointense on T1 and hyperintense on T2 (between callipers and yellow arrow respectively) with associated soft tissue oedema. c Sagittal T2-weighted image shows hyperintense neuroma in continuity (yellow arrows) along the ulnar nerve
