摘要
目的探讨肺硬化性血管瘤(PSH)的cT特征,提高对本病诊断的准确性。方法回顾性分析22例经手术、病理证实的PSH的cT特征,所有的病例均行cT平扫和动态增强扫描。结果病灶位于右肺者12例,左肺10例,4例位于肺门区,其余均位于肺外围;22例病灶呈圆形或椭圆形,14例病灶密度均匀(14/22,占63.63%),其中2例出现轻度分叶(2/22,占9.09%);8例病灶密度欠均匀(8/22,占36.36%),边缘可见点状钙化,1例可见“空气新月征”。增强以后均有比较明显的强化,密度值达90~148HU。病灶与周围血管关系密切。结论cT对于肺硬化性血管瘤的诊断有一定价值,增强扫描能更好的显示病变特点,对该病的诊断及鉴别诊断有重要意义。
Objective To evaluate CT features of pulmonary sclerosing hemangioma (PSH) , and improve the CT diagnostic ac- curacy of the disease. Methods CT features of PSH confirmed by operation and pathology were retrospectively analyzed. Con- ventional scan and contrast-enhanced scan were performed in all the cases. Results 12 lesions were in right lung, while 10 were in left, 4 lesions were located in hilum of lung. 14 lesions of the 22 cases showed a uniform density ( 14/22, 63.63% ) , two of which had slight lobulated shape ( 2/22, 9.09% ) ; 8 cases were not uniform in density and showed punctate calcification ( 8/ 22, 36.36% ) , one of which presented with air crescent sign; All the lesions enhanced obviously after contrast-enhanced scan and density was up to 90 to 148HU . The close relation between surrounding vessel and the lesions were found generally. Con- clusion The CT scanning is helpful for the diagnosis of PSH. Enhanced CT is valuable in diagnosis and better shows lesion of PSH.
