骨巨细胞瘤的临床特征与影像分析(附36例报告)

目的研究骨巨细胞瘤的临床特点和影像学特征。方法搜集经手术病理证实的36例骨巨细胞瘤,回顾性分析其临床表现、X线、CT及MRI影像学征像。结果20～40岁为最常见发病年龄,膝关节周围为最常见的发病部位。病变影像学特征囊状破坏伴有皂泡状表现22例,溶骨性破坏8例,骨骼变形伴骨外软组织肿块3例,侵犯邻近骨质4例,破坏区周围硬化增生2例,细层状骨膜反应2例。结论骨巨细胞瘤临床表现具有一定特点,X线平片是诊断骨巨细胞瘤的最基本方法,CT对于微细病变显示优于平片,MRI对脊柱、颅骨部位病变有较大价值。

Clinical and imaging analysis for bony giantcell tumor report of 36 cases

Objective To study the clinical and imaging features of bony giant-cell tumor(GCT). Method 36 cases with bony giantcell tumor confirmed by operation and pathology were reviewed in clinical features, radiography, CT and MRI. Results GCT common occurs at the age from 20 to 40, and predominantly arises around the knee joint. Imaging findings of lesion include cyst destruction accompanying soap bubble appearance in 22, lytic destruction of bone in 8, skeleton deformity as well as soft tissue mass in 3, eroding adjacent bone in 4, osteosclerosis like loop around lesion in 2, and spiculate periosteal reaction in 2. Conclusion GCT has some traits in clinics. Radiograph is a most common access to diagnose it. CT delineates minute lesions superior to radiograph, and MRI shows vital value for those lesions in spine and skull.
