PURPOSE: Primary @entity706 (PBL) is a rare type of @entity706 . Few data have been reported regarding the utility of @entity29786 in this disease. The aim of this study was to assess the role of @entity29786 in the diagnosis and therapeutic effect evaluation of PBL. MATERIALS AND METHODS: A total of 19 consecutive @entity1 with PBL were enrolled. Whole-body PET/CT scan was performed for all @entity1 . The diagnosis of PBL was established by histopathology and immunohistochemistry. RESULTS: @entity29786 was positive in 94.7% (18/19) of @entity1 . Uptake of FDG in lesions was intense with SUVmax of 15.14    11.82. @entity66 were found in 47.4% (9/19) @entity1 , while 52.6% presented with a single involved lesion. Based on the lesions, PET detected 98.9% (87/88) lesions. Among them, 71.6% (63/88) lesions were found to be located in axial skeleton and 28.4% (25/88) in the extremity skeleton. FDG PET/CT also found the lesions infiltrate to the surrounding soft tissue in 84.2% (16/19) @entity1 . On the syn-modality CT, the @entity79 was noted in 43.2% (38/88) of the lesions, of which 50.0% lesions presented as slight change in bone density and 50.0% as severe change. The diagnostic sensitivity of PET was much higher than that of CT (98.9% vs. 43.2%, P=0.000). PET/CT was performed for evaluation of treatment response in 13 @entity1 . In 12 @entity1 with complete response(CR), PET/CT found the 25 lesions were F-18 FDG fully resoluted after treatment, however, @entity79 was still presented in 72.0% (18/25) lesions. CONCLUSIONS: The present study suggests that @entity29786 was a sensitive imaging modality for diagnosis and treatment response evaluation of PBL.
