【摘要】：目的观察原发气道唾液腺型肿瘤[包括腺样囊性癌(ACC)和黏液表皮样癌(MEC)]的CT表现。方法回顾性分析经病理证实的22例气道ACC和23例MEC患者的CT表现。结果病变部位:ACC位于气管及主、叶支气管,以气管最多(12/22,54.55%),MEC位于段及以上各气道,以主支气管最多(9/23,39.13%)。ACC形态:气管腔内外肿物10例,气道壁弥漫增厚5例,肿物截断主支气管者4例,腔内宽基底肿物3例。MEC形态:气道腔内肿物20例,腔内外肿物2例,肿物截断主支气管者1例。密度:ACC平扫CT值24~35 HU、低于邻近胸壁肌肉,多轻度强化(14/19,73.68%);MEC平扫CT值40~60HU,4例伴少量钙化,多明显强化(16/20,80.00%)。结论气道唾液腺型肿瘤CT表现具一定特点,CT影像能较准确的显示病变部位、形态及其与周围组织的关系。
[Abstract]:Objective to observe the CT findings of primary airway salivary gland tumors (including adenoid cystic carcinoma (ACC) and mucoepidermoid carcinoma (MEC). Methods the CT findings of 22 cases of airway ACC and 23 cases of MEC were retrospectively analyzed. Results the location of ACC was located in trachea, main lobar bronchus and lobar bronchus, the most of which was trachea (12 / 22) 54.55%), MEC in each airway and above, and the most of main bronchus (9 / 2339.13%). ACC): 10 cases of intraluminal and intraluminal masses of trachea. There were 5 cases of diffuse thickening of airway wall, 4 cases of amputation of main bronchus and 3 cases of endobronchial mass. MEC morphology was as follows: 20 cases of intraluminal mass, 2 cases of intracavitary mass, and 1 case of mass truncating main bronchus. Density: the CT value of ACC plain scan was 24 ~ 35 HU, lower than that of adjacent chest wall muscles, and the enhancement was more mild (14 / 19, 73.68%); MEC, 40%, 60 HUU) than that of the adjacent chest wall muscles (CT value 40 / 60), and a small amount of calcification was found in 4 cases (16 / 20 80.00%). Conclusion CT findings of airway salivary gland tumors have some characteristics, and CT images can accurately display the location, morphology and the relationship between the lesions and the surrounding tissues.
