INTRODUCTION
Mycobacterium fortuitum and Mycobacterium peregrinum are nontuberculous mycobacteria (NTM). They belong to a subset of NTM known as rapid-growing mycobacteria (RGM), previously designated as Runyon class IV. Rapid-growing mycobacteria are saprophytic, ubiquitous in nature, and generally considered nonpathogenic. Several species of RGM, including M fortuitum and M peregrinum, are potentially pathogenic in humans. Mycobacterium fortuitum infections are typically cutaneous, occurring when the skin barrier has been breached. No pattern of infection by M peregrinum has been established. Herein, we discuss a pediatric case of otomastoiditis that progressed to petrous apicitis, intracranial empyema, and meningitis despite appropriate medical and surgical therapy. Initial laboratory identification in this case listed M fortuitum with a follow-up laboratory identification by the Centers for Disease Control and Prevention (CDC) listing the M fortuitum/M peregrinum group. Because the CDC . . . [Full Text of this Article]
