Abstract Objective: To investigate the influence factors and incidence rate for the focal patchy clouding opacity in lung adjacent to the anterior cardiophrenic angle(FPCOLACA) in normal adults. Methods: Five hundred cases(269 female, 231 male; mean age (53.8±15.5) years old) without relevant symptoms, tumor and sugery(including cough and sputum production), were analyzed retrospectively by using health examination chest CT scan. The FPCOLACAs incidence and its relationship with mental type, cardiothoracic ration, sex, age, obesity and focal pleura thickening were studied statistically. Results: Of all patients, there were 78 cases(15.6%) with the right FPCOLACA and 98 cases(19.6%) with the left FPCOLACA. Logic regression analysis showed that the FPCOLACA correlated significantly with the age and mental type(P<0.05), and not with the sex, obesity and focal pleura thickening(P>0.05). There were the higher incidence rates for the right FPCOLACA in the subjects with 55 years old or more and for the left FPCOLACA in the subjects with more 56 years old. There were the higher incidence rates for the FPCOLACA in the subjects with horizontal heart. Conclusion: The FPCOLACA displays in the healthy adults, and is not pathophysiology or clinical medicine significance, and it correlated with the age and mental type.
