Patient Data
Thickened synovial fold at the postero-lateral aspect of elbow joint namely radio-capitellar articulation measures about 10 length and 6mm in thickness. Associated bone marrow edema of the radial head and neck with focal osteochondral erosion of the anterolateral aspect of radial head (chondromalacia). Bone marrow edema of the capitellum with articular surface irregularity. Moderate elbow joint effusion.
Arrows on the sagittal T2 image points to thickened synovial fold and on the coronal STIR image point to bone marrow edema.
Case Discussion
Elbow synovial fold syndrome is the condition in which there is thickened synovial fold creating mechanical snapping with subsequent bony and cartilage changes. Patients tend to present with snapping pain and/or elbow locking during elbow flexion and extension.
