Abstract

Actinomyces meyeri is rarely isolated in cases of actinomycosis. The identification of A. meyeri had historically been difficult and unreliable. With the recent development of 16S ribosomal RNA (16S rRNA) sequencing, Actinomyces species such as A. meyeri can be isolated much more reliably. A. meyeri often causes disseminated disease, which can be secondary to frequent pulmonary infections. A penicillin-based regimen is the mainstay of A. meyeri treatment, with a prolonged course usually required. Here, we report a case of pulmonary actinomycosis with brain abscess caused by A. meyeri that was initially thought to represent lung cancer with brain metastasis.
