Objective To study the utility of CT for detection of small bone lesions in POEMS (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) syndrome. For patients with a solitary bone lesion, irradiation is a first-line treatment, whereas systemic chemotherapy is indicated for patients with multiple bone lesions. Therefore it is important to correctly identify the number of bone lesions.<br> Methods We studied the sensitivity of chest/abdomen/pelvic CT to detect bone lesions in 28 patients with POEMS syndrome. 99mTc-HMDP bone scintigraphy was performed in 14 patients, and the results were compared with CT.<br> Results CT showed multiple bone lesions in 68% of the 28 patients, and 71% of the lesions had a diameter <10 mm. In 14 patients who underwent both CT and scintigraphy, bone lesions were detected in 57% by CT and in 79% by scintigraphy, but the location and nature of the identified lesions were considerably different; CT frequently showed small lesions (diameter <10 mm) in the vertebrae and pelvis, which were not detected by scintigraphy, whereas scintigraphy could show lesions in the skull and long bones. Overall, by using both examinations, multiple bone lesions were found for 86% of patients.<br> Conclusion CT is particularly useful to detect small bone lesions. CT and bone scintigraphy are complementary, and therefore both should be performed for bone survey in POEMS syndrome.<br>
