目的探讨肺硬化性血管瘤(PSH)的影像学特点,提高其术前诊断的准确性。方法搜集11例经手术病理证实的PSH,将其影像学表现与手术病理结果进行回顾性对照分析。结果PSH影像表现多是肺孤立性肿块,密度不均匀,病变轮廓清楚,边缘光滑者10例,边缘不规则者1例;1例可见小的钙化,1例见空气新月征。CT增强扫描病灶明显强化,7例均匀强化,4例强化不均匀。CT与病理的关系是病变的高密度与低密度区分别对应于其血管瘤成分与囊变区。结论PSH的胸部平片和CT平扫无明确特征表现,增强扫描对病变的诊断和鉴别诊断起着关键作用。
Objective To investigate the imaging characteristics of pulmonary sclerosing hemangioma (PSH) and to improve the accuracy of its preoperative diagnosis. Methods 11 cases of pathologically confirmed PSH were collected, and their imaging findings and pathological findings were analyzed retrospectively. Results Most of the PSH images were lone solitary lumps with uneven density, clear outline of the lesion, 10 cases with smooth edge and 1 case with irregular edge. One case showed small calcification and one case showed air crescent sign. CT enhanced scan lesions were significantly enhanced, 7 cases of uniform enhancement, 4 cases of uneven enhancement. The relationship between CT and pathology is that the high and low density areas of the lesion correspond to their hemangiomas and cystic areas, respectively. Conclusion There is no clear characteristic of plain film and CT scan of PSH. Enhanced scan plays a key role in the diagnosis and differential diagnosis of the lesions.
