摘　　要：目的探讨儿童原发性大气道肿瘤的常见临床表现和CT特点。方法回顾性分析11例经手术和病理证实儿童原发性大气道肿瘤的临床和CT资料,术前11例患者均行CT平扫和增强扫描。发病年龄9个月~11岁。结果11例中包括6例黏液表皮样癌,3例炎性肌纤维母细胞瘤,2例血管瘤。本组中最常见的临床表现是咳嗽,占72.7%(8/11)。病灶最大径0.5~2.5 cm,平均(1.3±0.6)cm。6例支气管黏液表皮样癌中,2例表现为主支气管腔内结节灶,4例表现为肺叶支气管的管腔结节灶;4例明显强化,其中5例(5/6,83.3%)合并病灶远端肺组织不张和扩张支气管黏液栓形成。3例炎性肌纤维母细胞瘤中,左主支气管1例,右主支气管2例,2例腔内单发生长结节,1例累及腔内外,均呈轻度强化。2例血管瘤,颈段气管1例呈轻度强化,胸段气管1例呈明显均匀强化,均为腔内单发生长结节。结论儿童原发性大气道肿瘤的临床和CT表现具有一定特点,CT影像能较准确的显示病变部位及相关征象,对病因不明反复咳嗽的患儿有协诊作用。Objective To investigate the common clinical manifestations and CT characteristics of primary airway tumors in children.Methods The clinical records and preoperative unenhanced and enhanced CT of 11 children(age range:9 months-11 years)with pathologically confirmed primary airway tumors including mucoepidermoid carcinoma(6),inflammatory myofibroblastoma(3),and hemangioma(2)were retrospectively analyzed.Results The most common clinical manifestation was cough(8/11,72.7%).The maximum diameter of the lesion was 0.5-2.5 cm with an average of(1.3±0.6)cm.The 6 bronchial mucoepidermoid carcinomas presented as intraluminal nodules in the left/right main bronchus(2)or lobar bronchus(4)with marked contrast enhancement(4/6,66.7%)and associated mucus embolism in the dilated bronchus with distal atelectasis of the distal lung(5/6,83.3%).The 3 inflammatory myofibroblastomas presented as single elongated nodule in(2)or both inside and outside(1)the left(1)or right(2)main bronchus with mild contrast enhancement.The 2 hemangiomas presented as elongated nodules in the cervical trachea(1)with mild contrast enhancement and in the thoracic trachea(1)with marked uniform enhancement.Conclusion The clinical and CT features aid the diagnosis of primary airway tumors in children with recurrent cough of unknown etiology.
