| 目的 利用64层CT后处理图像包括横断面图像、冠状及矢状多平面重建(MRP)图像研究平片上显示的骨巨细胞瘤皂泡征的病理学意义。方法 对于病理证实的骨巨细胞瘤157例,回顾其平片及CT图像,统计其平片和CT表现包括平片上出现皂泡征的比例和皂泡征在CT上的表现。结果 骨巨细胞瘤平片上出现皂泡征的比例为11.46%(18/157),18例平片显示的皂泡征在CT图像上仅1例(5.56%)显示有一条完整骨性分隔,其余17例(94.44%)均显示为边缘突向病变内部的骨嵴。结论 骨巨细胞瘤平片上皂泡征出现率低,绝大多数平片显示的皂泡征不是真正的骨性间隔。 |

| Objective To study the pathological significance of soap-bubble sign demonstrated on plain film in giant cell tumor by post-processing images of 64-slice CT including axial images as well as coronial and saggital multiplannar reconstraction (MPR) images. Methods Retrospect plain films and CT images of 157 cases of pathologically proved giant cell tumor, count the emerging rate of soap-bubble sign on plain film, and analyze what is the sign like on CT. Results The emerging rate of soap-bubble sign on plain film was 11.46% (18/157). Eighteen cases of giant cell tumor demonstrated soap bubble sign on plain film, but only one of which (1/18, 5.56%) displayed integrated osseous septa on CT images and the other 17 cases (17/18, 94.44%) of which showed osseous ridge stretching from side to the internal part of the lesion. Conclusion The proportion of giant cell tumors showing soap-bubble sign on plain film is very low; the most of the soap bubble sign seen on plain film is not true osseous septa. |
