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 diphosphonate uptake in a patient with asymmetric polyarthritis.

A 33-year-old patient with asymmetric polyarthritis, skin lesions and joint pain underwent bone scintigraphy.Total body examination showed an extra-osseous uptake in periarticular soft tissue of knees joints.A detailed history checkup, physical examination g5210t-p90 and laboratory tests were carried out to understand the link between the extra-osseous uptake and the phosphonate binding olea europaea montra in periarticular soft tissue.

To improve the anatomical description of the soft tissue of the knees and to clarify the nature of the extra-skeletal 99m Tc methylene diphosphonate uptake, magnetic resonance imaging scan was performed.99m Tc-labeled phosphonate binding has been reported in a number of extra-osseous conditions, but to our knowledge, there are a few cases showing bone tracer uptake in polyarthritis.In polyarthritic patients, whole-body bone scintigraphy were useful in examining the whole joints and detecting possible dubious extra-osseous uptake; in fact, it is able to select subjects who require further in-depth analysis, for example, magnetic resonance imaging.
