continued pain and swelling following a right subcondylar fracture two weeks ago There appears to be discontinuity of the medial epicondyle of the humerus with a small avulsed fracture fragment which is displaced distally by approximately 5-6 mm (image 12, series 801). There is also edema within the lateral epicondyle. There is increased T2 signal within the soft tissues of the elbow, more prominently along the medial aspect, compatible with edema/inflammatory changes. There is a small amount of fluid in the elbow joint adjacent to the olecranon fossa with some enhancement of the synovium. The visualized tendons are intact. There is a lesion within the visualized mid to distal biceps muscle which demonstrates intrinsic T1 signal on fat-saturated images, increased T2 signal, and some enhancement. The surrounding fascial planes appear intact.
1. Avulsion fracture of the medial epicondyle with surrounding soft tissue inflammatory changes.2. T1 and T2 hyperintense lesion within the biceps muscle is non-specific. The differential includes strain/hemorrhage though facial planes appear relatively intact, an atypical hemangioma, or other soft tissue lesion. Follow up MRI is recommended to prove stability/resolution.
