目的分析肺硬化性血管瘤(PSH)的多排螺旋CT(MSCT)平扫、增强和多种后处理的表现,提高该病的影像学诊断能力。方法收集18例经病理证实的PSH患者的MSCT平扫、增强和多种后处理影像表现。结果 CT平扫均表现为边界清楚的圆形或椭圆形肿块性病灶;13例增强患者中有11例病灶均匀强化,2例不均匀强化;增强后CT值介于80-115Hu之间。结论中青年女性CT征象表现为单发、圆形或椭圆形、边界清楚伴均匀强化或空气新月征的肺内肿块时,应考虑到PSH的诊断。 Objective To analyze the performance of multi-slice spiral CT (MSCT) in the treatment of pulmonary sclerosing hemangioma (PSH), and to improve the imaging performance of the disease. Methods The MSCT images of 18 patients with pathologically confirmed PSH were collected and analyzed. Results CT scan showed a clear circular or oval tumor border lesions; 13 patients with enhanced lesions were uniformly enhanced in 11 cases, 2 cases of uneven enhancement; enhanced CT values ​​?? between 80-115Hu. Conclusions The CT findings of young and middle-aged women should be considered in the diagnosis of PSH when they manifest as solitary, round or oval, with clearly defined boundary and homogeneous enhancement or air crescent sign.
