不典型硬化性肺泡细胞瘤的CT诊断价值

目的探讨CT在不典型硬化性肺泡细胞瘤的诊断价值.方法回顾性分析2011年1月至2018年1月8例经病理证实的不典型硬化性肺泡细胞瘤患者临床、CT、病理资料.结果8例均接受CT检查,2例肿瘤形态为不规则,边缘分叶状,密度均匀,增强扫描中度不均匀强化;1例肿瘤形态为椭圆形,磨玻璃密度、不均匀,边缘略毛糙,轻度不均匀强化;1例肿瘤形态不规则,密度均匀,边缘毛刺,中度均匀强化,可见胸膜凹陷征;2例肿瘤为多发结节,类圆形,密度均匀,边缘光整,明显均匀强化;2例肿瘤圆形或椭圆形,密度均匀,边缘光整,无强化.8例均为CT不典型表现.结论不典型硬化性肺泡细胞瘤及早正确诊断非常重要,需要结合临床病史、化验报告及CT检查以提高诊断的准确率.

Objective To explore the value of CT in the diagnosis of atypical sclerosing pneumocytoma.Methods CT scans and clinical manifestarions of 8 cases with atypical sclerosing pneumocytoma confirmed pathologically after operation were analysed retrospectively.Results Of 8 cases received CT examination,2 cases with irregular shape,lobulatedshape,homogeneousdensity,moderately and heterogeneously enhanced tumors.1 case with oval shape,glassy density,heterogeneousdensity,mildly rough rim,mildly and heterogeneously enhanced tumor.1 case with irregular shape,homogeneous density,marginal burr,pleural indentationsign,moderately and homogeneously enhanced tumor.2 cases with several round or oval shape,dear rim,homogeneous density,homogeneously and obviously enhanced tumors.2 cases with round or oval shape,clear rim and homogeneous density,without reinforcement in enhanced CT.All 8 cases had atypical manifestation of CT.Conclusion Early and correct diagnosis of atypical sclerosing pneumocytoma is very important.Clinical history,laboratory report and CT examination need to be combined to improve diagnostic accuracy.
