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 released ulnar nerve is seen more anteriorly in a continuous fashion. Minimal signal is identified proximally yet specifically no abnormal enhancement, deformity or displacement. 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.Non-specific mild signal in the medial head of the triceps preventing exclusion of possible denervation. Please correlate with patient presentation given the appearance yet inconsistency with relayed history.
Medial epicondylar spur, see detail and pertinent negatives provided.
