| 摘 要： | 目的探讨椎体淋巴瘤MRI及正电子发射体层成像(PET)的影像特征及临床应用价值。资料与方法回顾性分析经病理证实的15例椎体淋巴瘤患者的MRI和PET表现,原发性骨淋巴瘤6例,继发性9例。结果MRI:原发性6例均为单一椎体压缩性骨折伴局部硬膜外和/或椎体旁软组织肿块,软组织范围超过病变椎体;继发性9例均为多椎体压缩性改变,7例伴硬膜外和/或椎体旁软组织肿块。椎体病变T1WI呈等或混杂信号,T2WI呈稍高信号。软组织肿块T1WI呈等/低信号,T2WI呈稍高信号,明显均匀强化5例,轻度均匀强化8例。PET:原发性6例均为术后PET检查,1例术后2个月显示局部复发,5例无异常;继发性9例(术前6例、术后3例)PET显示多椎体、淋巴结及脾葡萄糖代谢异常增高。结论椎体原发性淋巴瘤多为单椎体病变;继发性常为多椎体受累,两者均可伴硬膜外和/或椎体旁软组织肿块。椎体淋巴瘤MRI、PET表现无特异性,MRI能清晰显示椎管内病灶与脊髓的关系,PET对鉴别原发性与继发性淋巴瘤有重要价值。

| Abstract: | Objective To explore the imaging features and value of MRI and PET for vertebral lymphoma.Materials and Methods A retrospective analysis was taken to assess the MR imaging and PET appearance of 15 cases with vertebral lymphoma confirmed by pathological results,including primary lymphoma of bone in 6 cases and secondary lymphoma of bone in 9 case.Results MR imaging findings included:6 cases of primary lymphoma of bone were demonstrated as solitary vertebral compression fracture with local epidural-and/or par... |
