【摘要】：目的探讨原发性肺涎腺肿瘤的临床特点及CT表现。方法搜集经手术、纤支镜及病理证实的19例原发性肺涎腺肿瘤患者的临床病理与CT资料,回顾性分析其CT表现及临床特点。结果 19例原发性肺涎腺肿瘤中,腺样囊性癌11例(57.9%)、黏液表皮样癌8例(42.1%)。19例均为中央型,发生于气管及段以上支气管。11例腺样囊性癌中,6例位于气管,3例位于主支气管,2例位于叶支气管;6例(54.5%)呈环壁浸润生长,5例(45.6%)呈浸润生长并局部结节状突向腔内,病灶密度均匀,增强扫描欠均匀强化;3例(27.3%)合并肺不张,3例(27.3%)伴有纵隔淋巴结肿大,1例(9.1%)并肺转移,1例(9.1%)出现肝、双肾转移。8例黏液表皮样癌均发生于段或段以上支气管;3例(37.5%)呈圆形,5例(62.5%)呈不规则形,病灶密度欠均匀;3例(37.5%)增强扫描明显强化,5例(62.5%)呈轻或中度强化;2例(25.0%)伴纵隔膈淋巴结肿大,3例(37.5%)并远端肺不张及黏液栓塞表现。结论原发性肺涎腺肿瘤好发于段以上中央气道,CT表现具有一定特征性。腺样囊性癌浸润生长表现明显,黏液表皮样癌可伴有支气管黏液栓塞表现。
[Abstract]:Objective to investigate the clinical features and CT findings of primary pulmonary salivary gland tumor.Methods the clinicopathological and CT findings of 19 patients with primary pulmonary salivary gland tumor confirmed by surgery, fiberoptic bronchoscopy and pathology were retrospectively analyzed.Results among the 19 cases of primary pulmonary salivary gland tumor, 11 cases were adenoid cystic carcinoma, and 8 cases were mucoepidermoid carcinoma. All the 19 cases were of central type.Of the 11 cases of adenoid cystic carcinoma, 6 cases were located in the trachea, 3 cases were located in the main bronchus and 2 cases were located in the lobar bronchus in 6 cases (54.5%).The liver was found in 3 cases with atelectasis (3 cases with atelectasis) with mediastinal lymphadenopathy (1 case with 9. 1) and with pulmonary metastasis in 1 case (9. 1).8 cases of mucoepidermoid carcinoma with double kidney metastasis occurred in 3 cases of bronchiolus of segment or above (37.5%) were round and 5 cases (62.5) were irregular in shape.The density of the lesions was not even in 3 cases (37.5%) and enhanced obviously in 5 cases (62.5%). The lesions presented mild or moderate enhancement in 2 cases (25.0) and mediastinal lymphadenopathy in 3 cases (37.5%) and distal atelectasis and mucus embolism.Conclusion Primary pulmonary salivary gland tumors are characterized by CT findings above the central airway.Invasion and growth of adenoid cystic carcinoma were obvious, mucoepidermoid carcinoma could be accompanied by bronchial mucus embolization.
