    Abstract:
    BACKGROUND: Anaerobic bacteria are uncommon etiologic agents of acute mastoiditis in children. However, recent studies suggest an increase in the incidence of Fusobacterium necrophorum mastoid infections in the last two decades. METHODS: A surveillance study performed over 3.5 years in a tertiary pediatric medical center identified 7 children with acute F. necrophorum mastoiditis. Clinical, laboratory, and treatment data were collected by file review. RESULTS: Five of the 7 children presented in the last year of the study. All 7 children were less than 26 months old on admission, and none had a history of otogenic infections. All cases were characterized by significantly elevated levels of inflammatory markers. All were diagnosed as complicated mastoiditis with abscess formation. Four children had an epidural abscess, three children had evidence of osteomyelitis beyond the mastoid bone, and four children had imaging evidence of sinus vein thrombosis. All seven children required cortical mastoidectomy with ventilatory tubes insertion and two children required more than one surgical intervention. During follow-up, two children had recurrent episodes of mastoiditis due to other pathogens. CONCLUSION: Our data support the literature suggesting that the occurrence of F. necrophorum mastoiditis among children is rising. Acute coalescent mastoiditis due to F. necrophorum is associated with a complicated course and warrants particular attention by pediatricians, infectious disease experts, and ear, nose and throat specialists.
