【摘要】 目的探讨肺硬化性血管瘤(PSH)的CT表现及诊断价值。方法回顾性分析经穿刺活检及手术病理证实的肺硬化性血管瘤9例,对其CT表现和病理学特点进行分析。结果 9例中,按部位区分:左肺上叶2例,左肺下叶2例,右肺中叶4例,右肺上叶1例,均为单发病灶;按病灶形态区分:7例为结节状影,境界清晰,1例为长条状,1例为楔形影。CT平扫9例均呈软组织密度,1例边缘可见点状钙化,3例内部可见气体,呈空气新月征,其中3例行增强扫描,均明显强化,其中1例可见血管贴边征。结论肺硬化性血管瘤在CT平扫中具有良性肿瘤的普遍性特点,空气新月征及增强扫描对肺硬化性血管瘤的诊断有较高价值。更多还原

【Abstract】 Objective To analyze the CT characteristic and diagnostic value of pulmonary sclerosing hemangioma(PSH).Methods 9 cases pathologically proven PSH after biopsy or operation were included in this retrospective article.CT findings and pathology features were analyzed.Results All lesions were single.According to the parts distribution,there were 2 in superior lobe of left lung,2 in inferior lobe of left lung,4 in middle lobe of right lung,and 1 in superior lobe of right lung.According to the shape distribution,there were 7 nodules,1 strip,and 1 wedge.A soft-tissue dense was presented on pre-contrast CT in all 9 lesions.Calcification was found in one lesion;air was found in 3 lesions(air trapping sign).Obvious enhancement was found in all 3 enhanced scans.The vessels at its periphery sign was found in 1 lesion.Conclusion Universality of benign tumors was presented on CT plain scan in PSH.Air trapping sign and contrast enhanced scanning have a high diagnostic value for PSH.更多还原
