【摘要】：目的分析肺硬化型血管瘤(PSH)CT影像特点,提高对PSH诊断水平。方法收集经病理证实为PSH患者11例,全部病例均作胸部CT平扫及增强扫描,并对靶病灶进行薄层多方位重建,分析CT表现,总结影像学特点。结果 11例PSH,CT平扫均表现为肺内孤立性圆形、类圆形结节或肿块影,密度均匀,边缘光滑,无深分叶,增强扫描病灶均明显强化。病理以血管瘤样及乳头样组织结构为主者,强化明显而迅速;以实性及硬化性组织结构为主者,为渐进性明显均匀强化。结论肺硬化型血管瘤少见,CT表现具有一般良性肿瘤特征,但缺乏特异性,病灶周边出现"贴边血管征"、"空气新月征"可提示性诊断,确诊仍需病理学检查。
[Abstract]:Objective to analyze the CT features of pulmonary sclerosing hemangioma and improve the diagnostic level of PSH. Methods 11 cases of PSH proved by pathology were collected. Results all of the 11 cases showed solitary round pulmonary nodules or masses, homogeneous density, smooth margin, and no deep lobes. The lesions were obviously enhanced in contrast enhancement. The histopathology of hemangiomatous and papillomatous tissues was obvious and rapid, and that of solid and sclerosing tissue was the main one. Conclusion the rare CT findings of pulmonary sclerosing hemangioma have general benign tumor features, but lack of specificity, and "marginal vascular sign" and "air crescent sign" can be used as indicative diagnosis of pulmonary sclerosing hemangioma. The diagnosis still needs pathological examination.
