Patient Data

Age: 60 years
Gender: Male
MRI

Knee MRI

Thickening of the popliteus tendon at its insertion with adjacent mildly T2 hyperintense material and related lateral knee subcutaneous edema and lateral femoral condyle edema centered on the popliteal groove. A deposit of T2 hyperintense material is seen at the deep aspect of the medial collateral ligament origin. The appearances are characteristic of peri-tendinous/peri-ligamentous gout. There is also an incomplete radial tear of the medial meniscal posterior horn and a tiny inner free edge radial tear of the lateral meniscal body. 

Case Discussion

Characteristic appearance of periarticular knee joint gout with deposition of urate and inflammation centered around the popliteus tendon.
