摘　　要：目的探讨并总结肺原发性类癌的临床及影像表现。方法回顾性分析我院2012年12月至2019年12月病理证实为肺原发性类癌的9例患者的临床及影像资料,并回顾相关文献,总结其临床及影像学特征。8例进行CT平扫及增强扫描,1例行CT平扫。结果 9例中,男3例,女6例,年龄31~55岁,中位年龄43岁。3例位于支气管内,6例位于肺野内。其中7例表现为圆形或椭圆形结节,2例表现为不规则结节或团块;8例表现为边界清楚光整,1例表现为边缘毛糙;7例病灶密度均匀,2例有钙化点。CT增强扫描8例,5例见明显强化效应,CT值增幅超过30HU以上,其中1例强化不均匀,1例中度强化,2例见轻度强化。结论肺原发性类癌影像表现为支气管、肺内边界清楚的椭圆形或圆形结节,增强扫描轻度-明显强化,钙化少见,了解其临床与影像特征有助于诊断该疾病。Objective To explore and summarize the clinical and imaging manifestations of primary pulmonary carcinoid.Methods Retrospective analysis the clinical and imaging data of 9 patients with pathologically proven primary pulmonary carcinoid from December 2012 to December 2019,and review the literature,summarize the clinical and imaging features.8 cases CT scan and enhanced scan,1 case CT scan.Results 3 cases were male in 9 cases,female 6 cases,aged 31 to 55 years old,with a median age of 43 years.3 cases within bronchus,6 cases within lung field.Solitary round or ellipse tumors were shown in 6 cases,and other three cases appeared irregular.Clear and smooth boundary tumors were shown in 8 cases,and other 1 case appeared crude boundary.7 cases appeared homogeneous density,2 cases calcification.8 cases performed CT contrast scanning,5 cases appeared significant enhancement,which showed amplification of CT values exceed 30HU,and 1 case had uneven enhancement,1 case had moderate enhancement,and 2 cases had mild enhancement.Conclusion The imaging findings of primary pulmonary carcinoid include bronchus and pulmonary ellipse tumor with significant enhancement on CT contrast scan,with calcification at part cases.Understanding the clinical and imaging features help to check out the disease.
