ABSTRACT

Diagnosis: Tophaceous gout

History: 40 year old male with history of gout presents with chronic knee pain for 5 months.

Findings: There is no evidence of bone marrow abnormality. A small joint effusion is present. A large nodular mass is seen adjacent to the lateral superior patella with isointense signal on T1 and heterogeneous signal on T2 measuring approximately 5.2 x 1.8 x 6 cm. Smaller similar masses are present at the femoropopliteal insertion site, within the femoral notch and at the base of the Hoffa's fat pad just anterior to the anteromedial tibia. The PCL appears thickened but intact. The ACL, menisci, and collateral ligament complexes are unremarkable. Full thickness fissuring is present in the medial trochlea cartilage.

Ddx: >> Gout >> Pigmented villonodular synovitis >> Pseudogout >> Tumor >> Uric acid nephropathy >> Rheumatoid arthritis >> Sarcoidosis >> Amyloidosis

Dxhow: Needle biopsy

Exam: Right knee findings: Minimal warmth noted. No erythema. No subcutaneous nodules. Minimally tender to palpation along joint line. Full range with both active and passive motion. Negative anterior/posterior drawer sign.
