摘要
目的:探讨骨原发性淋巴瘤的MRI表现及其诊断价值。方法:对8例经手术病理证实,MRI资料完整的骨原发性淋巴瘤进行回顾性分析。8例均行MRI平扫和增强。结果:7例为单骨发病,1例为多发。7例为B细胞源性,1例为T细胞源性。病变在T1WI多呈等或稍低信号,T2WI多呈等或稍高信号,呈明显均匀或不均匀强化。8例均合并大小不等的软组织肿块影。结论:骨原发性淋巴瘤主要发生于脊柱和骨盆,多侵犯单骨。软组织肿块大、骨膜反应轻、T2WI信号不高,增强扫描多呈明显强化,是其相对特征影像学特点。平扫和增强MRI检查对骨原发性淋巴瘤定性诊断有较高的诊断价值。
Objective： To study the MRI findings of primary lymphoma of bone（PLB） and evaluate MRI scanning in the diagnosis of the disease. Methods： A retrospective analysis was made on imaging of 8 patients with pathologically proved PLB. The unenhanced and enhanced scanning was performed in all patients. Results： There was single bone involvement in 7 cases and multiple involvement in 1 case. Seven cases were B-lymphocytes, while 1 case was T-lymphocytes. Most of the lesions showed iso- or hypo-intense signal on T1WI and iso- or slightly hyperintense signal on T2WI. Lesions showed signifi- candy homogeneous or inhomogeneous enhancement. Various size soft-tissue masses were present in all cases. Conclusion： PLB mainly involved vertebrae and pelvis. There was single bone involvement in most cases of PLB. The comparatively typical features of MRI were a large accompanying soft tissue mass, slight periosteal reaction, and isointensity on T2WI with significandy enhancement. The plain and enhanced MRI scanning were all very helpful in the diagnosing of PLB.
