摘要: 目的:探讨脊柱腱鞘巨细胞瘤和骨巨细胞瘤影像表现异同点,以提高对此两种肿瘤的认识。方法:对7例病理确诊的腱鞘巨细胞瘤和30例骨巨细胞瘤的 CT 和 MRI 表现比较分析,总结其影像学表现的异同点。结果:7例腱鞘巨细胞瘤中5例位于颈椎以小关节为中心,2例位于胸椎椎体:3例呈膨胀性骨质骨破坏,5例骨破坏区周围见硬化边;30例骨巨细胞瘤中10例位于颈椎、14例位于胸椎、6例位于腰椎,18例呈膨胀性骨质破坏;27例肿瘤主体位于椎体,3例位于附件,2例骨破坏周围可见硬化边;肿瘤骨破坏部位有统计学差异、骨质破坏形式二组无统计学差异;硬化边形成与否具有统计学差异;4例腱鞘巨细胞瘤在 T2 WI 上呈等低信号、3例呈混杂信号;5例进行增强扫描:1例呈中等强化,4例明显强化;20例骨巨细胞瘤在 T2 WI 呈等低信号,8例呈混杂信号,2例呈稍高信号;21例进行增强扫描:8例呈明显均匀强化,12例不均匀增强,1例轻度强化;二组肿瘤的 MRI 信号、增强特点无统计学差异。结论:腱鞘巨细胞瘤和骨巨细胞瘤骨破坏形式、MRI 信号及增强无统计学差异,而病变部位及硬化形成与否二者具有统计学差异。 Objective:To investigate the similarities and differences of imaging manifestations between giant cell tumor of tendon sheath (GCTTS)and giant cell tumor of spine (GCTS)and to improve the knowledge of these two kinds of tumors.Methods:CT and MRI appearances of 7 pathologically confirmed GCTTS and 30 GCTS were compared and ana-lyzed,their similar and different features were summarized.Results:Five GCTTS located in cervical spine with the small joints as the center,vertebrae and two cases located in thoracic vertebra.Three cases showed expansive bone destruction and 5 cases with sclerosis rim formation.Ten of thirty GCTS were located in cervical spine,14 in thoracic spine and 6 cases in lumbar spine.Eighteen cases showed expansive bone destruction.Twenty-seven cases were located in the vertebral body,3 located in the appendages.The sclerotic rim was seen in 2 cases.The location had statistical difference between the two groups and the type of bone destruction had no statistical difference between the two groups.Sclerotic rim formation or not had statistical difference between the two groups;Four GCTTS showed isointensity to hypointensity and 3 cases showed heterogeneous signal on T2 WI.One showed moderate and four showed intensive enhancement among five cases.GCTS showed isointensity or hypointensity in 20 cases,heterogenous signal in 8 cases and slightly higher signal in 2 cases on T2 WI.After injection of contrast,8 tumor showed obviously homogenous enhancement,12 displayed heterogenous enhance-ment and one showed slight enhancement among twenty-one enhancement tumors.There were no statistical differences be-tween MRI signal and enhancement characters between the two groups.Conclusion:There were no statistical differences be-tween the two groups in type of bone destruction,MRI signal intensity and enhancement characters.There was statistical difference in tumor location and sclerosis rim between the two groups.
