Methicillin-resistant Staphylococcus aureus (MRSA) submandibular abscess in a neonate

Abstract

Neonatal suppurative submandibular sialadenitis and abscess formation is an exceedingly rare entity. This report describes a complex case of a male neonate with a methicillin-resistant Staphylococcus aureus (MRSA) submandibular abscess, requiring emergency intubation due to acute airway compromise. The patient was admitted to the paediatric intensive care unit, received appropriate antibiotic treatment and underwent urgent surgical drainage of the abscess. He made a full recovery and remains well 18 months later. No comorbidities or common risk factors for the disease were identified. Although extremely uncommon, neonatal submandibular abscesses can lead to significant morbidity. Neonates tend to present insidiously, and sudden clinical deterioration with airway compromise is possible. MRSA has been increasingly implicated in these infections, even in the absence of relevant risk factors. As such, continued clinical vigilance is essential for prompt diagnosis and prevention of life-threatening complications. Multidisciplinary input is paramount for appropriate management of these complex infections.
