目的:提高对肺硬化性血管瘤的CT表现和病理特征的认识。方法:经手术和病理证实的肺硬化性血管瘤19例,男2例,女17例。年龄10～72岁,平均40.9岁。经胸片、CT常规检查和靶扫描。结果:肺硬化性血管瘤的影像表现:肺内中外带孤立性球形肿块或结节,边缘光滑锐利,可有浅分叶或小钙化;瘤周可见包膜,包膜可钙化;瘤外周或瘤体内有时可见“空气新月征”;增强扫描病灶明显强化,并可见多量线样血管影,可出现“快进慢出”的强化表现;肿块周围组织、肺门、纵隔未见异常。结论:该病多见于女性患者,有良性表现的肺孤立性肿块,CT增强靶扫描对肺硬化性血管瘤的鉴别诊断有帮助。
Objective: To improve the CT findings and pathological features of pulmonary sclerosing hemangiomas. Methods: Surgical and pathological confirmed pulmonary sclerosing hemangioma in 19 cases, 2 males and 17 females. Aged 10 to 72 years old, average 40.9 years old. Transbronchial, CT routine examination and target scan. Results: The imaging manifestations of pulmonary sclerosing hemangioma: solitary spheroid mass or nodules in the middle and outer lungs, the edge is smooth and sharp, there may be shallow leaves or small calcification; peritumoral visible envelope, the capsule calcification; tumor peripheral or The tumor can sometimes be seen in the “air crescent sign”; enhanced scan lesions were significantly enhanced, and visible a large amount of line-like vascular shadow, there can be “fast forward slow” enhanced performance; tumor surrounding tissue, hilar, mediastinum See abnormalities. Conclusion: The disease is more common in female patients with benign solitary lumps of lung, CT enhanced target scan for the differential diagnosis of pulmonary sclerosing hemangioma helpful.
