The purpose of the present study was to evaluate whether 2-fluoro[fluorine-18]-2-deoxy-D: -glucose (F-18 FDG) positron emission tomography (PET) could differentiate malignant and benign bone lesions and whether obtaining delayed F-18 FDG PET images could improve the accuracy of the technique. ⋯ The results of this study indicate that dual-time point F-18 FDG PET may provide more help in the differentiation of malignant tumors from benign ones.

Medial dislocation of the patella is an unusual entity. It is usually an iatrogenic complication of surgical lateral retinacular release. ⋯ MR imaging confirmed the complete tear of the lateral patellar retinaculum and disclosed contusion of the anteromedial portion of the medial femoral condyle and lateral patella. This case is noteworthy because the injury patterns of patellar soft tissue restraints differ markedly from the classical features of lateral patellar dislocation.

Percutaneous osteoplasty (POP) as a technical extension of percutaneous vertebroplasty has been used as a treatment for osteolytic lesions in weight-bearing bones besides the vertebrae, and has demonstrated beneficial outcomes in terms of pain relief and functional improvement. However, its efficacy in non-weight-bearing bones is not well known. Herein, we present the case of a patient with an osteolytic lesion from multiple myeloma in the sternum, a non-weight-bearing bone, who obtained sustained pain relief and improvement of life quality after POP. These data suggest that POP may be an alternative treatment for osteolytic lesions in non-weight-bearing bones.

Randomized Controlled Trial Comparative Study
Accuracy of whole-body low-dose multidetector CT (WBLDCT) versus skeletal survey in the detection of myelomatous lesions, and correlation of disease distribution with whole-body MRI (WBMRI).
The aim of the study is to assess the feasibility of whole-body low-dose computed tomography (WBLDCT) in the diagnosis and staging of multiple myeloma and compare to skeletal survey (SS), using bone marrow biopsy and whole-body magnetic resonance imaging (WBMRI; where available) as gold standard. ⋯ WBLDCT at effective doses lower than previously reported, is superior to SS at detecting osteolytic lesions and at determining overall stage of multiple myeloma, and provides complementary information to WBMRI.
