[2025-10-02T06:04:52.669379] [PI reasoning] **Identifying a possible hydatid cyst**

I need to work with the image since it’s crucial for my diagnosis. Based on the description of a round white opacity in the right lung, it seems likely the question is about hydatid cysts, particularly common in pediatric cases. These cysts typically appear as well-circumscribed spherical masses and can lead to cough and fever in children. In contrast, abscesses show cavities, and consolidations have air bronchograms. I’ll support my answer with citations on hydatid cyst radiology shortly.
