摘要
目的:探讨原发性骨淋巴瘤的影像表现的诊断价值。材料和方法:回顾性分析经病理证实的15例原发性骨淋巴瘤的X线、CT及MR影像资料。结果:15例中骨盆受累7例、脊柱受累6例、肩胛骨及股骨受累各2例,肋骨受累1例。X线平片或CT检查的病例中,骨质破坏主要为溶骨型和浸润型12例,囊状膨胀型及混合型各1例,12例骨质破坏的周边可见不同程度的软组织肿块。MRT1WI信号类似或稍高于肌肉9例(9/11),T2WI信号高于肌肉低于脂肪10例(10/11),MR信号不均匀6例。结论:轻微的骨质破坏伴明显软组织肿块表现可提示原发性骨淋巴瘤的诊断,但需结合临床和病理确诊。
Purpose To discuss the diagnostic value of imaging findings of primary lymphoma of bone （PLB）. Materials and Methods The X-ray, CT and MRI images of 15 cases of PLB comfirmed by pathology were retrospectively analyzed. Results Among 15 cases of PLB, 7 lesions located in pelvis, 6 lesions in vertebral, 2 lesions in scapula, 2 lesions in femur and 1 lesion in rib. In the patients with examination of X- ray or CT, the type of osteolysis and infiltrating destruction of bone was demonstrated in 12 cases, and type of capsular dilate and mixed was in 1 case respectively. Delete soft tissue masses were found adjacent to bone destruction in 12 patients. On T1WI images, the lesions were demonstrated equal or slightly high signal compared with muscle in 9 cases （9/11）; on T2WI images, the signal intensity of lesion was higher than muscle and lower than fat in 10 cases （10/11）; 6 cases showed heterogeneous signal. Conclusions The sign of slight destruction of bone with obviously soft tissue mass maybe indicate the possibility of PLB, however referring clinic and pathology is necessary to final diagnosis.
