CT diagnosis of high altitude pulmonary edema / 中华放射学杂志

ABSTRACT

Objective To explore the value of CT diagnosis of high altitude pulmonary edema (HAPE). Methods The CT findings in 16 patients unfit to high altitude were analyzed. Results The findings on CT were as follows (1) The early stage of HAPE showed ground glass opacity, most of which located at the superior segment and posterior basis segment of inferior lobes, with the right lung to occur earlier than that of the left lung. (2)The advanced stage showed shaggy opacity. (3) The late stage lesions developed to posterior and apical segment of the superior lobes, air bronchus sign could be seen on involved segments. (4)Right lung was more serious than left lung. Conclusion CT was an ideal method to find HAPE. The accuracy of CT diagnosis in HAPE was 100%.
