摘要
目的 探讨骨孤立性浆细胞瘤（SPB）的影像学表现,以提高SPB的影像学诊断能力.方法 回顾性分析经手术或穿刺活检病理证实的16例SPB患者的临床和影像学资料.结果 16例均为单发病灶,X线及CT表现为膨胀性骨质破坏,边界较清楚,所有病例均无骨膜反应.与肌肉信号相比,T1加权像呈等或稍低信号,T2加权像呈高信号,所有病例均无明显瘤周骨髓水肿,但均可见不同程度的软组织侵犯.MR增强扫描,大部分病例表现为明显均匀强化.结论 SPB常呈膨胀性溶骨性骨质破坏,病灶边界多较清楚,多伴软组织侵犯或形成软组织肿块.X线、CT和MR联合检查有利于提高SPB的诊断准确性.
Objective To investigate the imaging features of solitary plasmacytoma of bone（SPB）,to improve the ability of imaging diagnosis of SPB.Methods Retrospective analysis by surgery or biopsy pathology confirmed 16 cases of patients with SPB clinical and imaging data.Results All lesions were single.X-ray and CT scan showed swelling bone destruction,boundary more clearly,in all cases no periosteal reaction.Compared with the muscle signal,T1-weighted images showed equal or slightly lower signal,T2-weighted images showed high signal.All patients had no significant peritumoral edema in the bone marrow,but were seen varying degrees of soft tissue invasion.Enhanced MR scan,most cases showed significantly enhanced uniformity.Conclusions SPB presents osteolytic destruction,expansive growth and soft tissue mass without bone reaction and peritumoral edema.X-ray,CT and MR together might improve the diagnostic accuracy of SPB.
