Multiple cystic translucent areas in the apical regions of both upper lungs are abnormal and may be caused by pulmonary alveoli, pulmonary cysts, emphysema, bronchiectasis, and so on. 1. Pulmonary alveoli: due to various factors stimulate the formation of unidirectional ventilation valve structure, resulting in gas into the alveoli is not easy to discharge, the internal pressure rises and rupture, which will appear in the performance of the bilateral upper apical region of the lungs multiple cystic translucent areas. 2. Pulmonary cysts: the cystic structure of the lungs may cause localized cystic cavity-like lesions, resulting in multiple cystic translucent areas in the bilateral upper apical regions of the lungs. 3. Emphysema: cystic dilatation due to blockage of small airways also manifests as multiple cystic translucent areas in both upper lung apices. 4. Bronchiectasis: repeated infections cause bronchiectasis, resulting in columnar bronchiectasis as well as cystic bronchiectasis, which may also be manifested as multiple cystic translucent areas in both upper lung apical regions. There are many reasons for the multiple cystic translucent areas in the apical regions of the upper lungs, and it is necessary to go to the hospital in time to complete the relevant examinations and follow the doctor’s instructions for treatment.
