Gallium-67 scintigraphy in polymyalgia rheumatica.

A patient with atypical presentation of polymyalgia rheumatica is presented. Her major symptoms were mild weakness, pain on passive movement of the shoulder and hip girdles, with mild tenderness but no joint stiffness. Muscle enzymes were within the normal range. The diagnostic work-up included gallium-67 scintigraphy, which showed intense uptake in both shoulders, with remarkable improvement following steroid treatment. A prospective study may delineate the possible role of this imaging modality in establishing a diagnosis of polymyalgia rheumatica.
