目的探讨肺硬化性血管瘤(PSH)的影像学特征,加深对本病的认识,提高诊断准确率。方法回顾性分析经手术病理证实的22例肺硬化性血管瘤的影像学表现及主要特点。结果 CT平扫表现为圆形或卵圆形孤立肿物,直径1.1~5.0cm,平均2.5cm,11例伴有贴边血管征,4例病灶周围伴晕征,2例病灶周边伴磨玻璃,2例伴空气半月征,1例伴钙化。22例全部行增强扫描,呈明显均匀或不均匀强化。结论肺硬化性血管瘤比较少见,CT平扫加增强扫描有助于提高诊断准确率。
Objective To investigate the imaging features of pulmonary sclerosing hemangiomas (PSH), deepen the understanding of the disease, and improve the diagnostic accuracy. Methods The imaging findings and main features of 22 patients with pulmonary sclerosing hemangiomas confirmed by surgery and pathology were retrospectively analyzed. Results CT scan showed round or oval isolated tumors, diameter 1.1-5.0cm, average 2.5cm, 11 cases with hemming vascular signs, 4 cases with halo around the lesion, 2 cases around the lesion with ground glass Two cases were associated with air semilunar syndrome and one case was associated with calcification. All 22 patients underwent enhanced scans and showed a uniform or uneven enhancement. Conclusions Pulmonary sclerosing hemangioma is rare, and CT plain scan plus enhanced scan can help improve the diagnostic accuracy.
