摘要
目的探讨脊柱孤立性浆细胞瘤的CT及MRI表现。方法对18例经病理证实的脊柱孤立性浆细胞瘤行CT检查,对其中9例行MR检查,观察脊柱孤立性浆细胞瘤的CT及MRI表现。结果脊柱孤立性浆细胞瘤可累及脊柱各节段,以胸椎最多。CT表现为椎体及附件的骨质破坏,以溶骨性骨质破坏最常见,可出现椎体压缩及轻度骨质疏松。MR T1WI和T2WI均以低信号为主。结论脊柱孤立性浆细胞瘤以椎体及附件的溶骨性骨质破坏为主要表现,病灶易侵及椎旁或硬膜外间隙;MRI显示病灶较CT敏感、清晰。
Objective To explore CT and MRI appearances of spinal solitary plasmacytoma. Methods Eighteen patients with pathologically proved spinal solitary plasmacytoma were retrospectively reviewed. CT was performed in all 18 cases, MRI was performed in 9 cases, and CT and MRI appearances were observed. Results Spinal solitary plasmacytoma in- volved spine of each segment, mainly in thoracic spine. The characteristics of these lesions were usually osteolytic of verte- bral body and appendix, Vertebral compression frac：tures and osteoporosis was also seen in some lesions. The signal inten- sity was mainly hypo on T1WI and hypo on T2WI. Conclusion Spinal solitary plasmacytoma lesions usually present osteo- lytic destructions, and tend to involve paraspinal or extradural space. MRI is more sensitive than CT in detecting lesions of spinal solitary plasmacytoma.
