Granulicatella adiacens Causing a Parapharyngeal Abscess in a 10-Month-Old Infant: A Rare-Case Report and Literature Review of Deep Neck Infections (DNIs) in Children.

is a rare variant of the Streptococcus bacteria. When isolated, has been described in cases of endocarditis and bacteremia, but less commonly seen in isolated pyogenic infections. We report a case of a parapharyngeal abscess caused by in an otherwise healthy 10-month-old infant, which was successfully treated with antibiotics and surgical drainage. To the best of our knowledge, this is the first described case of a pediatric deep soft tissue neck infection caused by with one other report in an adult. Additionally, of all localized infections from this bacteria, this is only the second reported case in the pediatric population. We also include an evidence-based literature review of the clinical presentation, microbiology, imaging modalities, and management approach to deep neck infections (DNIs).
