The Gram stain of the aspirate showed branched gram-positive rods (Fig. 2) and, suspecting actinomycosis, we changed the antimicrobial agent from cefazolin to meropenem (0.5 gx3/day).
Chest computed tomography: Mass shadows are seen in the left lung field.

We suspected the possibility of disseminated lesions based on the results of the bacterial species identification and performed cerebral, chest, pelvic, and leg CT scans and magnetic resonance imaging, by which multiple abscesses were detected in the parenchyma, left lung, and right thigh (Fig. 3, Fig. 4, Fig. 5).
