Elbow Synovial Fold Syndrome

摘要

We present the case of a 17 year old female with elbow synovial fold syndrome (aka plica synovialis). The etiology is thought to be related to repetitive microtrauma resulting in thickening of normal elbow synovial folds. Associated symptoms typically worsen over time, particularly with increasing exercise and motion. While radiographs are unrevealing, MR imaging will show a thickened plica, oftentimes with secondary signs of plica impingement. The following report reviews presentation, pathophysiology, characteristic imaging findings and current treatment options for elbow synovial fold syndrome.
