骨巨细胞瘤影像学表现特点分析

Imaging Findings Characteristic Analysis of Giant Cell Tumor Bone

目的探讨骨巨细胞瘤的X线平片、CT、MRI及ECT全身骨显像的影像学表现特点。方法回顾性分析经手术病理证实17例骨巨细胞瘤的影像学表现。结果 17例患者中,10例发生于长骨骨端;3例发生于脊柱;足部3例;髂骨1例。影像表现为偏心性、膨胀性骨质破坏,周围无明显硬化,骨皮质变薄,连续性可中断;ECT全身骨显像多表现为环状放射性摄取增加。结论骨巨细胞瘤的X线表现具有一定的特征,CT和MRI能显示骨巨细胞瘤内部结构,MRI显示骨巨细胞瘤周围软组织及骨髓侵犯有优势,ECT全身骨显像及局部SPECT/CT对骨巨细胞瘤范围进行评估,可发现多中心骨巨细胞瘤或转移病灶。X线平片结合CT、MRI及ECT全身骨显像可提高骨巨细胞瘤诊断准确率,为临床确定治疗方案提供重要依据。

Objective To analyze the imaging findings characteristic of X-rays,CT,MRI,and ECT,The whole body bone imaging in giant cell tumor of bone. Methods The imaging features were retrospectively analyzed in 17 cases of giant cell tumor of bone proved by operation and pathology. Results Of 17 cases, 10 cases occurred in long bone in the extremities.3 cases occurred in the spine.Foot 3 cases. IIium 1 case. Images show the partical centrality,dilatability bone destruction, no obvious hardening around,thinning of the bone cortex,continuity interruptible;ECT, the whole body bone imaging performance for annular radioactivity uptake increased moer. Conclusion X-ray manifestation of giant cell tumor of bone has certain characteristics. CT and MRI can show giant cell tumors of bone structure. MRI showed giant cell tumors bone surrounding soft tissue and bone marrow involvement. ECT, the whole body bone imaging to evaluate scope of giant cell tumor, central giant cell tumors of bone or metastatic lesions can be found. X-ray plain film combined with CT, MRI and ECT, the whole body bone imaging can impove the giant cell tumor diagnosis accuracy, provide important basis for dinical to determine treatment plan.
