Abstract

Streptococcus pneumoniae is a prevalent cause of pediatric acute otitis media (AOM) cases. Mastoiditis continues to be a significant complication of AOM. Data obtained following the use of 13-valent pneumococcal conjugate vaccines (PCV13) have shown that in children with AOM, PCV13 serotypes from tympanocentesis or spontaneous ear drainage decrease and the probability of colonization of PCV13 serotypes in the nasopharynx is lower. In this paper, we aimed to report a case of mastoiditis and subperiosteal abscess caused by the S. pneumoniae 19A serotype that is penicillin resistant developing in a three-year-old patient with full PCV13 vaccination and normal immunity. Although PCV13 is included in the National Immunization Program of Türkiye, penicilin resistant S. pneumoniae serotype 19A should be kept in mind as a potential cause in complicated mastoiditis cases in patients with full PCV13 vaccination who have normal immunity.
