Patient Data
The quadriceps fat pad is enlarged of high signal on PD fat sat and T2 best seen on axial PD fat sat with mass effect on the adjacent suprapatellar recess and quadriceps tendon.
Small linear hyperintensity of the posterior horn of the medial meniscus with no extension to the articular surface, grade 2a according to the MRI grading system for meniscal signal intensity.
Normal appearance of the cruciate/collateral ligaments.

The clinical presentation and the MRI features are most consistent with a quadriceps fat pad impingement syndrome.
