technetium-tc-99m-medronate and Synovial-Cyst

The appearance of an intraosseous ganglion on a static bone scan has been described. This report describes the appearance on triple phase bone scanning, and discusses the implications for differential diagnosis of similar benign-looking subarticular cystic lesions of bone.

A case is reported of an infected popliteal (Baker's) cyst demonstrated with triple phase skeletal scintigraphy. Although double-contrast arthrography and ultrasonography are currently the modalities most frequently employed to diagnose the presence of popliteal cysts, they may also be detected utilizing this radionuclide technique in the course of evaluation for knee joint disease or septic arthritis. Radionuclide studies may be more sensitive for the evaluation of associated inflammatory disease involving the knee joint.

Intraosseous ganglia are benign cystic lesions of bone located in close relationship to the articular cartilage. The typical location and roentgenographic appearance of this lesion should permit a diagnosis of this entity which should be considered in the differential diagnosis of benign lesions of bone. Appearance of this lesion on a bone scan is shown in this case report.
