CT manifestations and pathological basis of pulmonary sclerosing hemangioma

Objective To study the CT features of pulmonary sclerosing hemangioma(PSH)to improve the accurate diagnostic rate.Methods CT image data of 10cases with PSH were retrospectively analyzed.All of the 10cases underwent plain chest CT scan,and 6cases underwent plain and enhanced CT scan.Results In all of the 10cases,there were 11lesions,including 6lesions located in left lung and 5lesions located in right lung.All lesions were mass or nodule in shape of round,with smoothly margin and diameter of 1.2-8.6cm.Diameter of 9lesions were less than 3.0cm.3lesions were with lobule.Pleural synedhia were in 3lesions.Densities of 7lesions were uniformity,with CT value of 26-53Hu and average value of 32.6Hu.Calcification like sand could identified in 3lesions.Air meniscus sign could be found in 2lesions.After injection of contrast medium,6lesions showed obviously enhancement,CT value of which increased to 59-86 Hu.Blood vessel marginating could be observed in 2lesions.Conclusion PSH could have certain CT features.If these features are found in middle-aged and elderly women,PSH should be considered and diagnosed by pathology detection.
