CT Image Feature Analysis of Pulmonary Sclerosing Hemangioma
-
摘要: 目的:探讨肺硬化性血管瘤的CT表现特征,以提高其CT诊断准确性及鉴别诊断的能力。方法:回顾性分析18例经手术和病理证实的肺硬化性血管瘤的CT表现,其中11例行CT增强扫描。结果:术前诊断有一定的难度。中年女性为主要发病群体。女性17例(17/18,占94.44%),43~70岁之间共15例(15/18,占83.33%)。发病部位集中于左下肺(9/18,占50.00%)。18例肺内类圆形肿块边界清楚,6例见斑点状钙化(6/18,33.33%),3例见浅分叶,1例有纵隔淋巴结肿大,所有病例均无空洞,无胸膜凹陷和受侵,无血管切迹征。CT值为26~40Hu。11例增强CT中10例(10/11,占90.91%)病灶呈明显强化,有一定的延迟强化,CT值增加46~60Hu以上。结论:CT对于肺硬化性血管瘤的准确诊断具有一定的价值,增强CT是必要的补充手段。Abstract: objective: To study the CT feature of pulmonary sclerosing hemangioma (PSH), and improve the diagnosi's accuracy and differential diagnosis of PSH by CT scanning. Methods: The CT images of 18 PSHs confirmed operation and pathology were retrospectively analyzed, and 11 cases followed enhanced CT scanning. Result: It is very difficulty in preoperative diagnosis and main group of PSH is middle-aged women. Of those 18 cases, female were found in 17 cases (17/18, 94.44%), and patients aged in 43-70 years were found in 15 cases (15/18, 83.33%) and whose tumors were located in the left lower lung zone accounted for 50.00%. The tumors were round with clear edge (18/18, 100/%), were slightly lobulated (3/18), had punctate calcification (6/18, 33.33%), and had mediastinal lymph node (1/18). All cases were without cavity, pleural sag and metastasis, and vascular incisura. The CT values of observed cases were between 26-40 Hu. Among 11 cases followed enhanced CT scanning, 10 cases showed obvious enhancement and delay enhancement to a degree, and the CT values were increased over 46-60 Hu. Conclusion: The CT scanning is helpful for the diagnosis of PSH. Enhanced CT could be helpful to diagnosis,
