摘要
孤立性肺结节(SPN)是指肺内直径≤3cm且边界清楚的单发病变。由于病变较小,其临床表现及影像学特征通常不典型,多在查体时发现。良性SPN种类繁多,包括肺结核、错构瘤、硬化性血管瘤、肺炎性肌纤维母细胞瘤(PIMT)等。笔者选取了在PET/CT显像中表现为高摄取而易出现误诊的2例良性病变,即肺结核和PIMT,对二者临床特征及影像学表现进行分析回顾、总结经验,以期从中得到启发,提高日后工作中临床医师对良性SPN诊断的准确率。
A solitary pulmonary nodule (SPN) is a single,well-circumscribed nodule with diameter less than 3 cm.The clinical manifestations and imaging features of SPN are usually atypical because of the small size and it is often found during physical examination.There are many kinds of benign SPN,including tuberculosis,hamartoma,sclerosing hemangioma,pulmonary inflammatory myofibroblastoma tumor and so on.Tuberculosis and pulmonary inflammatory myofiblastic tumor,which are easily misdiagnosed because of high uptake in PET/CT imaging,were selected.The clinical features and imaging manifestations of the two lesions were analyzed and reviewed in order to get inspiration and improve the diagnostic accuracy of benign SPN in future work.
