A roundish translucent shadow in the upper lobe of the right lung may be a pulmonary bulla formed by chronic obstructive pulmonary disease or emphysema.
A roundish translucent shadow is a common term used in imaging. The presence of a rounded translucent shadow in the lungs is often considered to be a possible pulmonary hernia. Combined with a medical history for symptoms such as cough, sputum, and dyspnea, as well as a pulmonary function test, the cause can be clarified.
In addition, lung CT can be used to clarify the size and nature of the lesion. If the size of the pulmonary herpes is small and the clinical symptoms are mild, observation is sufficient. However, if the volume is large, there will be the possibility of spontaneous rupture of the pulmonary herpes, which requires surgical treatment.
Usually, you should avoid strenuous exercise, quit smoking, eat a light diet, and seek medical attention immediately if you feel unwell.
