临床资料男,10岁,主诉间断咳嗽6个月余。胸部CT示:右肺下叶肿块并肺炎(图1A),内镜下活检病理示:肺粘液表皮样癌,低级别。正电子发射型X线断层显像-计算机断层扫描成像(PET-CT)显示右肺下叶体积缩小并斑片状及结节状密度增高影,代谢稍增高,提示右肺下叶不张并炎性病变,右肺下叶结节,代谢无异常,纵隔4、7区多发软组织结节,代谢稍活跃。表皮因子受体(EGFR)基因18,19,20,21号外显子检测范围内均未见突变,检测范围内未发现棘皮动物
Male, 10 years old, complains of intermittent cough for more than 6 months. Chest CT showed: the right lung lobes and pneumonia (Figure 1A), endoscopic biopsy pathology: lung mucoepidermoid carcinoma, low-grade. Positron emission tomography-computed tomography (PET-CT) showed a decrease in the volume of the right lower lobe and an increase in the density of patchy and nodular shadows, with a slightly increased metabolism, suggesting that the right lower lobe atelectasis was inflammatory Lesions, right lower lobe nodules, no abnormal metabolism, mediastinal 4,7 area multiple soft tissue nodules, metabolism slightly active. There was no mutation in the exons of Epithelial-Factor Receptor (EGFR) Genes 18, 19, 20, and 21, and no echinoderms were detected in the detection range
