Extra-osseous Tc methylene diphosphonate uptake detected enlargement of the knee joint in patient with polyarthritis
Bone scintigraphy is a nuclear scanning test used to find abnormalities in the skeleton.Certain abnormal processes involving soft tissues can also cause skeletal accumulation of radiotracer during bone scintigraphy.We present a case of periarticular knee soft tissue 99m Tc methylene CBT diphosphonate uptake in a patient with asymmetric polyarthriti
