Edema and convex bulging (AP diamater: 14 mm) of the suprapatellar fat pad (compare it to the prefemoral fat pad which retains its normal apperance). The edematous changes also involve the posterior fibers of the quadriceps tendon. Minimal knee joint effusion. Signs of prior partial tear or contusion of the anterior horn of the lateral meniscus.
Case Discussion
Findings are altogether in line with anterior suprapatellar fat pad impingement syndrome. The associated signal changes in the quadriceps tendon suggest tendinitis, which is a common association.
