Ulnar nerve pain There is a small focus of increased signal intensity involving the ulnar nerve at the level of the elbow joint best appreciated on series 4 image 15. Otherwise the ulnar nerve appears normal in signal intensity and caliber throughout its visualized course. The course of the ulnar nerve is delineated on PACS and is best seen on series 4, 7, and 10. There is no abnormal enhancement following contrast administration although visualization of the nerve on the postcontrast sequences is somewhat limited. There is skin irregularity and enhancement along the posterior medial aspect of the elbow likely relating to prior surgical intervention. Enhancement of the soft tissues is thought to represent scarring and there are small foci of signal void relating to prior surgical intervention. There is no abnormal signal intensity within the musculature surrounding the elbow. Although not tailored for the evaluation of the ligamentous and tendinous structures of the elbow, the ulnar collateral ligament and origin of the common extensor tendons are poorly visualized which likely relates to chronic tearing.The marrow signal intensity of the distal humerus, proximal radius, and proximal ulna is normal.
Small focus of increased signal intensity involving the ulnar nerve at the level of the elbow joint which is nonspecific but may reflect a minimal neuritis. Otherwise the ulnar nerve demonstrates normal signal intensity and caliber.
