Presentation
Lateral elbow severe pain. Pain worsens on activity.
Patient Data
The common extensor origin appears mildly thickened and shows altered hyper-intensities and calcific foci. Partial thickness interstitial tear noted at the humeral extent. The underlying lateral epicondyle shows normal signal intensities.
The postero-lateral aspect of the elbow shows mild skin and subcutaneous thickening.
Radial nerve shows normal signal intensity with no entrapment. Radial collateral ligament shows mild thickening, but no tear.
Radio-capitellar joint space small volume effusion noted. No evidence of abnormal distension of the bicipital radial or olecranon bursa.
The calcific foci at the common extensor origin are well seen on CT images.
Case Discussion
This is a pretty much straight forward case. Reporting points for radiologists:
-
common extensor tendon assessment:
- look for thickening with altered signal intensities
- the presence of abnormal soft tissue signal intensity (granulation tissue) between the common extensor tendon and radial collateral ligament
- identify tear or avulsion
- look for calcific focus
-
radial collateral ligament:
- thickening with altered signal intensities
- the presence of tear
- lateral epicondyle bony changes
- look for radial nerve entrapment
