摘要
目的探讨骨孤立性浆细胞瘤(SPB)影像学表现。方法收集经手术病理或活检证实的24例骨孤立性浆细胞瘤的临床和影像学资料,回顾性分析其影像学特征。结果所有患者均为单发病变,发病部位:脊柱10例(胸椎2例、腰椎4例、骶椎4例),扁骨10例(髂骨4例、耻骨3例、肩胛骨3例),长骨4例(肱骨2例、股骨2例)。X线和CT表现为膨胀性溶骨性骨质破坏,膨胀程度差异较大,内见粗糙或细小骨性间隔、如皂泡或蜂窝状,未见骨膜反应。脊椎和扁骨病灶突破骨包壳形成软组织肿物。长骨病灶3例局限于髓腔内,1例突破骨皮质。MRI可清楚显示病灶侵犯骨髓及周围软组织情况,但信号表现不一。结论 SPB、尤其是分化差的SPB的影像学表现缺乏特征性。CT和MR联合应用是目前SPB的最佳影像学检查方法。
Objective To explore the imaging features of solitary plasmacytoma of bone （SPB）. Methods Clinical and imaging data of 24 patients with SPB confirmed with pathology were collected and analyzed retrospectively. Results All patients had single lesion, located in the spine （n= 10, including 2 thoracic vertebrae, 4 lumbar vertebrae and 4 sacral ver- tebrae）, in flat bones （n= 10, including 4 iliac bones, 3 pubic symphysis and 3 scapula ） or in long bones （n=4, including 2 humeri and 2 femurs）. The imaging features of X-ray and CT appeared as swelling dissolved osseous bone destruction in different degrees, with visible rough or small bony septum such as soap bubble or honeycomb without obvious periosteal re- action. Lesions of spin and flat bone broke bone cladding, forming soft tissue tumor. Long bone lesions were limited in the medullary cavity in 3 patients, and breakthrough of cortical bone was noticed in 1 patient. The bone marrow and surround- ing soft tissue invasion were displayed clearly by MRI, but the signals of lesions were various. Conclusion Imaging mani- festations of SPB, especially of those with low differentiation are often lack of characteristics. Combination of CT and MR is the best imaging inspection for SPB at oresent.
