摘　　要：目的探讨硬化性肺泡细胞瘤(SP)的CT表现,以提高临床诊断水平。方法回顾性分析16例SP的临床、病理及CT表现。结果男2例,女14例。其中14例(87.5%)≥50岁。15例单发,1例多发。15例病灶光滑。圆形8例,椭圆形5例,浅分叶2例,多发团簇结节状1例。7例"贴边血管征",6例病灶边缘磨玻璃影,2例"鸟蛋-鸟巢征",5例"空气潴留征"。2例患者合并原位腺癌。1例患者穿刺活检病理怀疑微浸润性腺癌或原位腺癌,而随后的手术切除病理标本为SP。1例硬化性血管瘤伴神经内分泌分化(神经内分泌肿瘤)。结论瘤体形态及瘤周的特征性表现对病灶做出良性判断以及鉴别其他肿瘤具有重要的提示作用。Objective To demonstrate the computed tomography（ CT） features of sclerosing pneumocytoma（ SP）.Methods Sixteen cases of pathologically proven sclerosing pneumocytoma were included in this retrospective review. Results Female patients of SP were markedly frequent（ n = 14,87. 5%）. 14 patients ≥50 years old. These nodules（ n =15） were round（ n = 8）,oval（ n = 5）,mildly lobulated（ n = 2） in shape with a smooth boundary. Among the 16 patients,15 patients had a single lesion,1 patient had multiple lesions. The presence of overlying vessel sign（ n = 7）,halo sign or GGO（ n = 6）,egg and bird’s nest sign（ n = 2）,air-trapping sign（ n = 5） were the features in our cases. Two of 16 patients had two tumours in the lung,with the histopathology of SP and adenocarcinoma in situ,respectively. One case had been suspected for adenocarcinoma in small biopsies. Another case of SP with neuroendocrine differentiation（ neuroendocrine tumor）. Conclusion The features of tumor morphology and tumor periphery have important implications for the diagnosis and differential diagnosis with other tumors.
