摘要
目的 为了提高对脊柱多发骨髓瘤 (multiplemyeloma,MM)和转移瘤的影像诊断水平。方法 回顾性总结经骨髓涂片或局部病灶活检病理证实的脊柱多发骨髓瘤 17例 ,脊柱转移瘤 32例 ,分析二者的MRI特点 ,归纳其影像表现的差异。结果 脊柱多发骨髓瘤累及 15 4个椎体 ,其中累及附件 18个 ,占 11 7% ;椎体破坏变形 8个 ,占 5 2 % ;椎旁软组织多呈“围髓”生长。转移瘤累及椎体89个 ,多为跳跃状分布 ,累及附件 4 5个 ,占 5 0 6 % ;椎体破坏变形 5 1个 ,占 5 7 3% ,椎旁软组织常以破坏区为中心生长。结论 MRI检查在鉴别脊柱多发骨髓瘤和转移瘤中可以提供可靠的信息。
Objective To evaluate the MRI features of multiple myeloma (MM) and metastases in the vertebral column. Methods The MRI of 17 cases of MM and 32 cases of metastases proved by histology in the vertebral column were analyzed retrospectively. Results In MM,154 vertebra were involved,in which 18 appendixes were implicated,the rate was 11.7%; 8 vertebra bodies were destroyed and metamorphosed,the rate was 5.2%; and soft tissue mass was always around the spinal cord.In metastases,89 vertebra were involved and the distribution was capering,in which 45 appendixes were involved,the rate was 50.6%; 51 vertebra bodies were metamorphosed,the rate was 57.3%,and soft tissue mass was always around the focus of destruction.Conclusion MRI is helpful in differentiating MM from metastases in the vertebral column.
