脊椎巨细胞瘤的影像学诊断(附22例分析)

Imaging Diagnosis of Giant Cell Tumor of the Spine

目的；探讨脊椎巨细胞瘤的影像学诊断。材料与方法：经手术和病理证实的脊椎巨细胞瘤22例，回顾性分析其影像学表现。结果：14例颈、胸、腰椎巨细胞呈囊样或膨胀性破坏，其中11例呈偏心性，8例累及附件件有椎间盘变窄者7例，多椎体病变者3例；6例破坏区有分隔样骨嵴，4例合并椎体压缩骨折，5例出现椎旁软组织肿块。8例骶椎巨细胞瘤均位于骶椎中上部偏一侧为主。本组病例造成脊髓或马尾神经压迫8例。结论：脊椎巨细胞瘤主要表现为椎骨膨胀性破坏，常偏于一侧和累及附件，后期可侵犯相邻椎骨和椎间盘。CT和MRI对本病的诊断有重要价值。

Purpose: To evaluate the imaging diagnosis value in giant cell tumor of the spine. Materials andmethod: The imaging appearances of 22 cases with vertebral and sacral giant cell tumor were analyzed retrospectively. Results:The 14 patients with spinal involvement above the sacrum had an expansile and lytic destruction invertebral body or neural arch. Most lesions were off the axis,The disc-space narrowing was found in 7 cases. Themulti-vertebral body were involvement in 4 cases. The destructive area is soap bubble pattern or lightly trabeculated in 6 cases on plain films. The collapse of vertebral body in 4 cases,the 4 cases developed a paravertebal softtissu mass,the & cases with sacral involvement showed a well-circumscrbed radiolucency lesion off the central axisin the superior two-third of the sacrum. Conclunsion :Giant cell tumor of the spine commonly is expansion and lytic destuction which frequently affect the neural arch. In final stage,the adjacent vertebra or disc may be involved.CT and MRI is very useful in the diagnosis of the giant cell tumor of the spine.
