CT Image Feature Analysis of Pulmonary Sclerosing Hemangioma

objective:To study the CT feature of pulmonary sclerosing hemangioma(PSH),and improve the diagnosis 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.
