Two Cases of Invasive Infections Caused by Arcanobacterium haemolyticum in Immunocompetent Adult
Abstract
Arcanobacterium haemolyticum is a gram-positive bacillus that is most commonly implicated in pharyngitis and infections of the skin and soft tissue. Systemic and deep-seated infections caused by this organism are rarely reported in the literature. Recently, we encountered two cases of invasive infections caused by A. haemolyticum. We describe two cases, one with vertebral osteomyelitis with an epidural abscess and the other with a buttock abscess with bacteremia.

Sagittal MRI images of case-1. (A) T1 weighted image. (B) Gadolinium-Enhanced image. Intervertebral disc is severely destroyed. Epidural abscess is visible in the T1 and enhanced T1 image (arrow).
Figure 2
Axial MRI images of case-1. (A) T1 weighted image. (B) Gadolinium-Enhanced image. Epidural abscess that compressed the dural sac is visible in the T1 and enhanced T1 image (arrow). (C) Gadolinium-Enhanced image shows an abscess on the right iliopsoas muscle (arrow).

CT images of case-2. A CT scan shows fluid collection with air bubbles in the right buttock (arrow).
