【摘要】：目的 :统计正常成人前心膈角区肺内局灶性斑片状高密度影(Focal patchy clouding opacity in lung adjacent to the anterior cardiophrenic angle,FPCOLACA)的发生率,探讨其影响因素。方法 :回顾性分析2015年1月—2016年4月我院行胸部CT平扫的常规体检人员。所有人员均无咳嗽、咳痰等肺部相关症状;无肺部肿瘤、结核及大片渗出病灶等疾病;无心脏疾病;既往无肺部、心脏手术史;无心、肺、胸廓发育畸形。最后在符合标准的受检者中随机抽取500例作为研究对象,包括女269例,男231例,年龄(53.8±15.5)岁。统计FPCOLACA的发生率,利用Logic回归分析探讨其与心型、心胸比、性别、年龄、肥胖程度及局部胸膜增厚之间的关系,以P0.05为差异有统计学意义。结果:500例受试者中右侧FPCOLACA为15.6%,左侧为19.6%。Logic回归分析显示FPCOLACA和年龄、心型有关(P0.05),和性别、肥胖程度和局部胸膜增厚无关(P0.05)。右侧FPCOLACA常见于≥55岁者,左侧常见于56岁者。横位心更易出现FPCOLACA(P0.05)。结论 :正常成人可以出现FPCOLACA,它是没有重要病理生理及临床意义的影像征象,其出现与年龄、心型有关。
[Abstract]:Objective: to investigate the incidence of focal flaky high density patchy clouding opacity in lung adjacent to the anterior cardiophrenic (FPCOLACA) in the anterior phrenic angle area of normal adults. Methods: from January 2015 to April 2016, routine chest CT scan was performed in our hospital. There were no lung related symptoms such as cough, expectoration and sputum, no lung tumor, tuberculosis and massive exudative lesions, no heart disease, no history of lung surgery, no heart, lung and thoracic deformity. Finally, 500 subjects were randomly selected, including 269 females and 231 males, aged 53.8 卤15.5 years. The incidence of FPCOLACA was analyzed and the relationship between FPCOLACA and cardiac type, cardiothoracic ratio, sex, age, obesity degree and local pleural thickening was studied by Logic regression analysis. Results the right FPCOLACA was 15.6and the left was 19.6.Logic regression analysis showed that FPCOLACA was related to age, heart type, sex, obesity and local pleural thickening. The right FPCOLACA was more common in the patients over 55 years old and in the left side in the 56 years old group. In transverse position, FPCOLACAA P0.05 is more likely to appear. Conclusion: FPCOLACA can be seen in normal adults. It is an imaging sign with no important pathophysiological and clinical significance, and its appearance is related to age and cardiac type.
