<i>Citrobacter Sedlakii</i> as a Rare Cause of Brain Abscess in a Late-Preterm Omani Infant: <i>Case report and literature review</i>.

Brain abscess in neonates is rare but remains a severe, life-threatening complication of meningitis with significant morbidity and mortality. While <i>Citrobacter koseri</i> and <i>Citrobacter freundii</i> are commonly implicated in brain-abscess formation, <i>Citrobacter sedlakii</i> is an uncommon causative pathogen. To date, only two cases of neonatal brain abscess caused by <i>C. sedlakii</i> have been reported in the literature. Early diagnosis, timely surgical intervention and prompt antibiotic therapy are critical to achieving a favourable outcome. A third case of a <i>C. sedlakii</i> brain abscess in a preterm infant, presenting in 2024 to a tertiary-care hospital in Oman, is reported together with a brief review of the literature.
