title: Bilateral generalised synovial chondromatosis of the knee: Bone scintigraphic demonstration with radiologic correlation.
abstract: A 67-year-old woman with a history of bilateral progressive knee pain and swelling was referred for (99m)Tc-methyl diphosphonate bone scintigraphy. Flow and blood pool images showed bilateral heterogeneous increased uptake and delayed phase revealed mass-looking lobulated heterogeneous increased activity in both of knees extending distal part of the femoral shaft, but no other pathologic uptake was found in rest of the body. A diagnosis of synovial chondromatosis was made when correlated with X-ray and computed tomography.(CT) images. This is a rare presentation of generalized synovial chondromatosis involving both knees which demonstrated on bone scintigraphy with X-ray and CT correlation.
