【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T2WI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T2WI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。
[Abstract]:Objective: to investigate the differences and similarities between giant cell tumor of spinal tendon and giant cell tumor of bone. Methods: Ct and MRI findings of 7 cases of pathologically diagnosed giant cell tumor of tendon sheath and 30 cases of giant cell tumor of bone were compared and analyzed. Results of the 7 cases of giant cell tumor of tendon sheath, 5 cases were located in the cervical vertebra with the facet joint as the center. 2 cases were located in the thoracic vertebra vertebral body: 3 cases showed expansive bony bone destruction. 5 cases showed sclerosing margin around the bone destruction area. 10 cases were located in the cervical spine. Cases were located in thoracic vertebrae, 6 cases were located in lumbar vertebrae, 18 cases had expansive bone destruction, 27 cases had tumor body located in vertebral body, 3 cases were located in adnexal bone, 2 cases had sclerosing edge around bone destruction. There was statistical difference in the site of tumor bone destruction, but there was no significant difference in bone destruction between the two groups. There was statistical difference in the formation of sclerosing margin. 4 cases of giant cell tumor of tendon sheath showed iso-low signal intensity on T2WI, 3 cases showed mixed signal and 5 cases underwent enhanced scanning. 1 case showed moderate enhancement and 4 cases showed moderate enhancement. 20 cases of giant cell tumor of bone showed isospermia in T2WI. 8 cases showed mixed signal, 2 cases showed slightly high signal intensity, 21 cases underwent enhanced scan, 8 cases showed obvious homogeneous enhancement, 12 cases showed uneven enhancement, 1 case showed slight enhancement. There was no significant difference in MRI signal enhancement between the two groups. Conclusion: there was no significant difference in MRI signal and enhancement between giant cell tumor of tendon sheath and giant cell tumor of bone.
