目的：探讨CT、MRI对脊椎孤立性浆细胞瘤（SPS）的诊断价值，提高对该病的认识。。方法收集经病理证实的7例SPS，回顾性分析其CT、MRI影像表现。结果病灶位于胸8椎体1例，胸12椎体3例，腰3椎体1例，腰1椎体2例。7例均表现为不同程度溶骨样、虫蚀样骨质破坏，膨胀性生长，均可见软组织肿块形成。5例骨质破坏区周围有硬化边，内见残存骨嵴。 MRI增强扫描软组织肿块明显强化；5例病灶可见“微脑征”，4例可见“袖套征”，7例瘤周均未见明显骨髓水肿信号，5例发生不同程度病理性压缩骨折，6例合并椎管狭窄。结论 CT、MRI可明确显示SPS病灶的形态特点及与邻近组织的关系，“微脑征”及“袖套征”等影像特点具有一定特征性，有助于其诊断。

Objective To assess CT and MRI features for diagnosing solitary plasmacytoma of spine (SPS). Methods CT and MRI of 7 patient with pathologically confirmed SPS were retrospectively analyzed . . . Results The lesions involved the eighth thoracic (1), twelfth thoracic (3), first lumbar (2) and third lumbar (1) vertebrae. Variable degree of expansile bone destruction with contrast enhancing soft tissue mass was seen in all 7 patients. Other features included sclerotic rim and remnant of bone within the lytic bone lesion (5), mini brain sign (5) and cuff sign (4) associated with varying degrees of vertebral compression fractures (5) and spinal stenosis (6). There was no bone marrow edema in any of the lesions. Conclusion CT and MRI display the relationship between SPS and adjacent tissues clearly. Mini brain and cuff signs are features that may aid diagnosis of SPS.
