Question
The lung examination revealed a patchy area of increased density. After one week of anti-inflammatory medication treatment, a follow-up CT scan showed that the shadow still exists. The doctor said that there is no need to worry if there are no symptoms and allowed discharge. Should I be concerned about this shadow?
Answer
Firstly, it’s important to understand whether the lung CT scan was performed due to symptoms or routine examination. If it was due to respiratory symptoms such as coughing, sputum production, and fever, these shadows may be blurred patchy changes. Generally, lung shadows caused by infection usually disappear gradually with the relief of symptoms and the subsidence of inflammation after anti-inflammatory and anti-infection treatment. Therefore, there is no need to be overly concerned.
