摘要
目的 评价脊柱骨巨细胞瘤的影像学表现。资料与方法 回顾性分析 16例脊柱骨巨细胞瘤的CT和MRI表现 ,全部病例均经穿刺或手术病理证实。结果 发生于颈椎 8例 ,胸椎 1例 ,腰骶椎 7例。除 7例侵犯相邻2个椎体 ,余均累及 1个椎体。除单纯溶骨性破坏和椎体压缩性改变各 1例外 ,CT主要表现为椎体偏心性、膨胀性破坏。 10例MRI检查中除 2例巨大软组织肿块的病灶中可见无强化的囊性信号外 ,8例为T1WI稍低信号 ,T2 WI稍高信号 ,增强扫描均匀强化。
Objective To evaluated the imaging manifestations of the spinal giant cell tumors.Materials and Methods CT and MRI findings in 16 patients with pathologically proved spinal giant cell tumor were retrospectively analyzed. Results The lesion was located at cervical vertebra in 8, at thoracic vertebra in one and at lumbosacral portion in 7 cases. The lesion affected two neighboring vertebrae in 7 cases, and affected only one vertebra in the remaining 9 cases. Pure osteolytic destruction or vertebral compression was seen in one case each. The main CT sign was eccentric, expanding bone destruction. Of 10 cases having MRI scans, huge soft tissue mass with non-enhanced cystic signal inside was seen in 2, and low signal on T 1WI while high signal on T 2WI was seen in 8. All lesions showed homogenous enhancement on enhanced scans.Conclusion CT and MRI are of high value in the diagnosis of spinal giant cell tumor.
