Vague opacity in the right lower lung infrahilar region and retrocardiac region on lateral view, which may represent a confluence of normal structures; however, without prior studies, the chronicity or acuity cannot be determined. If acute pulmonary symptoms are present, this could indicate early consolidation. Follow-up radiograph after treatment or comparison with outside prior radiographs is recommended. Consideration for follow-up evaluation with chest CT if clinically warranted.
