| Sumario: | Objective: Multiple myeloma(MM) is a malignancy of clonal plasma cells. Osteolytic lesions represent a criterion for symptomatic myeloma and are associated with bone loss, pathological fractures, and osteoporosis. Skeletal surveys with other sophisticated techniques and dual-energy x-ray absorptiometry (DEXA) are used to screen lytic lesions, and bone mineral loss, respectively. Here, we aimed to investigate the detection rate of osteolytic lesions and bone mineral loss by several imaging techniques in MM. Methodology: Three-hundred and ten symptomatic MM patients were screened retrospectively. The results of radiological techniques were recorded. The detection rate of osteolytic lesions, fractures, and plasmacytomas by imaging techniques, as well as bone mineral loss with DEXA was recorded. Also, associations with gender, MM type, lytic lesions, and osteoporosis were investigated. Results: Skeletal survey and PET-CT detected lytic lesions in 71.3% and 81.2% of patients, respectively. PET-CT had a sensitivity of 96.1% and specificity of 90.6% to detect lytic lesions. MRI was only used for patients with suspicious fractures and detected them for all patients who underwent MRI. The osteoporosis rate was 83% for 113 patients who underwent DEXA. Any association between lytic lesions and gender or MM type was not detected. Conclusion: Our study demonstrated that osteolytic lesions are not correlated with gender or MM type. PET-CT is a sensitive and specific method for detecting osteolytic lesions. Although DEXA is sensitive, its specificity is limited to detect osteoporosis in patients with lytic lesions. |
