Pain and weakness following ulnar nerve transposition Exam limited secondary to absent prior comparison imaging as well as extensive postsurgical findings including punctate blooming artifact throughout the area in question. Within this limitation the following observations are made including focal signal abnormality in the overlying medial epicondyles with a small bone spur (circled). Overlying postsurgical scarring and soft tissue changes are observed yet the expected ulnar nerve is not distinctly observed. Specifically no abnormally enhancing nerve or abnormal signal on STIR imaging. No discrete MR findings to suggest fascial bands, abnormal soft tissue, cysts or ganglia are identified. No synovitis. The ulnar collateral ligament and retinaculum are intact.
Medial epicondylar spur, see detail and pertinent negatives provided.
