A Case of Prefemoral Fat Pad Impingement Syndrome Caused by Hyperplastic Fat Pad

Figure 1

Preoperative MRI. Axial T1 MRI (a), axial STIR MRI (b), and sagittal STIR MRI (c) revealed the prefemoral fat pad (white arrowhead). The fat pad was located superolaterally to the PF joint, and hyperplasia was confirmed. There were no fibrous septa or mild peripheral enhancement patterns that were suggestive of lipoma.
