肺硬化性血管瘤CT表现及病理对照研究

The compare of CT features and pathologic type of pulmonary sclerosing hemangioma

目的:探讨肺硬化性血管瘤(PSH)的螺旋CT表现及与病理分型的关联性。方法:回顾性分析32例经手术病理证实的PSH的CT表现,所有病例均行平扫及增强扫描。结果:32例患者均为单发,其中男1例,女31例;位于右肺19例,左肺13例,最大径为1.1～7.2 cm,有6例位于肺门区,其余26例均位于肺外围。所有病例边界清晰,5例出现钙化结节,增强后大部分病例呈明显异常强化,增强后CT值为70～137 Hu,与病理类型明显相关,血管瘤型强化明显,硬化型强化较低。结论:PSH CT表现符合良性肿瘤的特点,与病理结果一致,不同病理类型其CT表现略有不同,

Objective：To compare the relevance of CT enhancement characteristic and pathology of pulmonary sclerosing hemangioma （PSH）. Methords ：The CT characteristic of 32 PSH patients were retrospectively analyzed,in- cluding conventional scan and contrast-enhanced scan. Results ~All of the 32 lesions were single, 1 lesions was male, 31 lesions was female,19 lesions were in right lung,13 lesions were in left lung,maximum gauge was 1.1-7.2 cm,6 le- sions were in lung area,others were in the periphery of lung. All has Clear boundary, 5 lesions has calcific nodules,the most has abnormal strengthen,the CT value was 70-137 Hu after enhancement,which related to pathological type, the reinforcement of angiomatous type was obvious ,the reinforcement of constrictive type was lower. Conclusion ：PSH is a kind of benign tumor,it is in keeping with pathology results,the CT manifestation is different in different patho- logic types,it is in keeping with pathology types.
