肺硬化性血管瘤的CT征象与临床病理研究

摘要

Objective To recognize pulmonary sclerosing hemanagioma(PSH) by investigated its CT and clini-copathologic characters. Method Data of 20 cases with PSH, all of which were confirmed pathologically, were col-lected and reviewed, including their clinical symptoms, CT features, and the pathological findings of PSH. Results The PSH presented as solitary, well-circumscribed, round or oval nodules or masses on CT pictures in all of the 20 cases. 12 of the 20 lesions were strong and homogenous enhancement on contrast enhanced CT scans. There were not hilar and mediastinal lymph node enlargement and lung metastatic tumor in all 20 patients. Under a microscope, PSH was composed of four histologic components-namely, solid, papillary, sclerotic and hemangiomatous. A neoplasm had at least two of them. Conclusion It is favourable to recognizing PSH that investigated its CT and clinicopathologic characters.%目的：研究肺硬化性血管瘤（PSH）的CT征象与临床病理特征，提高对PSH的认识水平。方法收集2007—2013年我院经手术病理证实的PSH 20例。分别回顾性总结分析其CT影像资料及PSH病理资料。CT的评价征象包括病变形态、密度、边缘、分布位置及增强前后CT值的差值。PSH病理资料包括组织形态结构与细胞学形态。结果20例PSH的CT均表现为单发、边缘清楚的圆形或是类圆形肿块，12例行增强扫描者均表现均匀显著强化。20例PSH均未发现肺门及纵隔淋巴结肿大，肺内亦未见转移灶。显微镜下，PSH主要由实体型、乳头型、硬化型和血管瘤型4种组织学形态，单个瘤体包括至少2种或2种以上组织形式。结论了解PSH的CT与病理特征，有利于提高对PSH的认识与诊断正确率。
