Spinal Epidural Abscess in an Infant Presenting as Fever and Respiratory Distress.

A 9-month-old healthy female presented during winter to the emergency department with a chief complaint of fever and prominent respiratory symptoms. She was discharged on oseltamivir with a presumptive diagnosis of influenza. She returned to the emergency department 2 days later with continued fever and more upper respiratory symptoms. She was admitted for intravenous hydration to the observation unit with a diagnosis of viral illness (with viral testing that returned positive for adenovirus) and dehydration. When her high fevers continued, bloodwork that was concerning for leukocytosis, elevated inflammatory markers, and elevated alkaline phosphatase was obtained. During her workup for fever, a full body magnetic resonance imaging was performed, which revealed the diagnosis of a C3 to L5 spinal epidural abscess. This case demonstrates the difficulty of making this important diagnosis in a preverbal child presenting with a concurrent virus during winter viral season.
