Radiography, bone scan, and F-18 FDG PET/CT imaging findings in a patient with Paget's disease

초록

Background A 52-year-old female patient sought evaluation at our hospital for an incidental abnormal finding on an abdominal radiograph. Methods The initial radiograph showed irregular sclerotic changes involving the right pelvic bone. At the same time, bone scintigraphy showed intense hot uptake in the right iliac and pubic bones. CT images showed characteristic thickening of the pelvic brim, suggesting the mixed phase of Paget's disease. Results The level of alkaline phosphatase (ALP) was 266 IU/l. 18F-FDG PET/CT images also showed diffusely increased 18F-FDG uptake in the right pelvic bone. However, the findings of 18F-FDG PET/CT were less notable than those of bone scintigraphy. Conclusion We report the imaging findings of a patient with Paget's disease evaluated by radiography, bone scintigraphy, and 18F-FDG PET/CT. © Korean Society of Nuclear Medicine 2010.
