A, Frontal chest radiograph shows a right lower lung mass. This finding is nonspecific. B, Rib detail radiograph shows subtle periosteal reaction (arrowheads) with erosion of the inferior rib cortex (arrow) consistent with chest wall invasion. Biopsy of the right lung mass recovered Actinomyces israelii.
