【摘要】 目的:探讨肺硬化性血管瘤(SHL)的影像特点,提高其术前诊断的准确性。材料和方法:搜集11例经手术病理证实的SHL,其中男3例,女8例,平均48岁。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:SHL多好发于女性,影像表现是孤立肿块,轮廓清楚,边缘光滑整齐,有时可见小的钙化和孤立性淋巴结肿大及纵隔向患侧移位。“含气新月征”具有特征性,但不常见,可见界限清楚的高密度和低密度区,高密度区强化显著,低密度囊变区无强化。并见增粗迂曲的肺门血管与病灶相连。结论:胸部平片和CT平扫仅能做出定性诊断,增强扫描尤其是薄层双期扫描对病变的诊断和鉴别诊断起着关键作用。更多还原

【Abstract】 Objective To evaluate the imaging characteristic of sclerosing hemangioma and to improve the accurate rate of its diagnosis before surgery. Methods Eleven cases of sclerosing hemangioma proved by surgery or pathology were analyzed. There were 3 males and 8 females. The mean age was 48 years old. The imaging findings of these cases were analyzed retrospectively according to surgery and pathology. Results Sclerosing hemangioma of lung usually occurred in female patients of middle age. The findings of imaging included solitary masses with clear and smooth margin sometimes with slight calcification and solitary mediastinum enlarged lymphadenopathy moved towards the masses. The "air crescentic sign" was its characteristical CT findings but was seen occasionally inside the masses. Sometimes the masses showed high and low density with clear border. High density areas demonstrated a homogeneours enhancement and low ones were slightly enhanced. There were thick and round blood vessels of lung between the tumor and hilum. Conclusion The plain chest film and plain CT can only diagnose the diseases. Contrast enhanced CT scan of thin section with double phase is very important to improve the diagnosis and differential diagnosis.更多还原
