目的观察肺硬化性血管瘤的多层螺旋CT表现,分析多层螺旋CT对肺硬化性血管瘤的诊断价值。方法回顾性分析12例经手术及病理证实的肺硬化性血管瘤的CT表现,12例术前均行胸部CT平扫和增强扫描,对增强扫描的图像进行薄层和三维重建处理。结果 CT平扫示肿瘤呈圆形或卵圆形肿块,位于右肺7例,左肺5例;边缘光整8例,有浅分叶4例;肿块密度均匀9例,病灶内见点状钙化3例。增强扫描均明显增强。结论 CT薄层和三维重建处理能清晰显示肿瘤良性表现,增强扫描显示肿瘤明显增强,与邻近血管关系密切是肺硬化性血管瘤的典型CT表现,多层螺旋CT对肺硬化性血管瘤的定位和定性诊断具有很高的临床应用价值。
Objective To observe the multi-slice spiral CT findings of pulmonary sclerosing hemangiomas and to evaluate the diagnostic value of multi-slice spiral CT in the diagnosis of pulmonary sclerosing hemangiomas. Methods The CT findings of 12 cases of sclerosing hemangiomas confirmed by surgery and pathology were retrospectively analyzed. Thoracic CT scan and enhanced scan were performed in 12 cases, and the images of the enhanced scan were reconstructed by thin layer and three-dimensional reconstruction. Results CT scan showed a round or oval tumor, located in the right lung in 7 cases, 5 cases of left lung; marginal light in 8 cases, shallow lobes in 4 cases; mass density in 9 cases, Calcification in 3 cases. Enhanced scanning were significantly enhanced. Conclusion CT thin layer and three-dimensional reconstruction can clearly show the benign tumor manifestations, enhanced scan showed that the tumor was significantly enhanced, adjacent to the blood vessels closely related to the typical CT sclerosing hemangiomas, multi-slice spiral CT sclerosing hemangiomas And qualitative diagnosis has a high clinical value.
