Pediatric spinal blastomycosis: case report.

A 5-year-old male patient presented with flank pain, limping, weight loss, and cachexia. Magnetic resonance imaging revealed destructive vertebral changes, an epidural mass, psoas abscesses, and lack of involvement of the disc spaces. Blastomyces dermatitidis was isolated from a needle aspiration specimen. Sparing of the disc spaces, an unusual finding, suggested that the spread of infection was by way of paravertebral structures and surrounding potential spaces. Management was simplified by using gadolinium contrast-enhanced magnetic resonance imaging, which indicated that the epidural mass was mainly solid, thereby obviating abscess drainage.
