What is Patchy opacity in lateral right lung base?

Patchy opacity in the lateral right lung base refers to an abnormal area observed on a chest imaging study, such as an X-ray or CT scan, where the lung tissue appears denser or less transparent than surrounding areas. This can indicate various conditions, including infection (like pneumonia), inflammation, or fluid accumulation (such as pleural effusion). Further evaluation, including clinical correlation and possibly additional imaging or tests, is often necessary to determine the underlying cause of the opacity.
