A rounded translucent shadow in the left lung apex is considered to be a possible cause of pulmonary herniation due to chronic obstructive pulmonary disease and emphysema.
Patients with rounded translucent shadows at the lung apex may have chronic cough, sputum, dyspnea, chest tightness and other clinical symptoms. Diagnosis needs to be based on pulmonary function tests to further determine the presence of the above problems, and regular chest CT examinations are needed.
For the emergence of rounded translucent shadows at the lung tip, alveoli should be considered. Regular chest CT should be performed to observe whether the size of the translucent shadows has become smaller or larger, and it is necessary to avoid smoking, upper respiratory tract infections, and violent coughing, otherwise the alveolus may rupture and lead to pneumothorax.
For patients with roundish translucent shadows at the lung apex, consult the respiratory medicine department of a regular hospital for a definitive diagnosis.
