99m-Tc HMDP bone scintigraphic findings of gouty arthropathy of both hands: extending soft tissue uptake adjacent to the joints.

The 99mTc hydroxy methylene diphosphonate scintigraphic findings of both hands are correlated to the radiographic findings in a patient with a 30-year history of gouty arthropathy. Scintigraphic differentiation of the type of arthritis on the basis of uptake pattern is difficult. However, the findings of rheumatoid arthritis are confined to the joints and usually the involvement is symmetrical. With gout there is a tendency toward asymmetrical, bilateral, multifocal joint involvement with areas of intense abnormal uptake; because of the associated soft tissue swelling, the intense uptake usually extends beyond the involved joints.
