摘要:
目的:研究骨巨细胞瘤(GCT)的X线平片、CT、MRI影像学表现,分析误诊的原因,提高诊断准确性。方法:搜集30例手术病理证实的GCT病例,回顾性分析其术前X线平片、CT平扫、MRI影像学表现。结果:GCT发生于股骨远端13例,胫骨近端6例,股骨近段4例,肱骨近端3例,桡骨远端2例,腰椎1例,髂骨1例。术前误诊5例,约占16.7%。结论:X线平片、CT和MRI从不同角度反映GCT的病理特征,合理结合三种检查方法,能更全面显示GCT的影像学特征,有利于诊断及鉴别诊断。
Abstract:
Objective: Analyze the imaging appearances of X-ray, CT and MRI in giant cell tumor of bone (GCT) and the causes of misdiagnosis to improve the diagnostic accuracy. Methods: Collect 30 cases of GCT confirmed by operation and pathology and analyze the X-ray, CT and MRI imaging findings retrospectively. Results: 13 cases located in distal femur, 6 in proximal tibia, 4 in proximal femur, 3 in proximal humerus, 2 in distal radius, l in lumbar spine, and 1 in iliac bone. There are 5 cases, about 16.7%, mis-diagnosed before operation. Conclusion: X-ray, CT and MRI reflect the pathological changes of GCT from different aspects. Combining the three methods of imaging can display the GCT imaging features well and conducive to diagnosis and differential diagnosis.
