CASE PRESENTATION

A 4-year-old-boy presented to the Children’s Hospital Colorado emergency department with acute-onset altered mental status. Two weeks before presentation, he had experienced several days of fever and persistent rhinorrhea with congestion. He awoke on the morning of admission with sudden-onset frontal headache and rapidly became obtunded. He was taken by ambulance to a nearby emergency department, where he was intubated for altered mental status. Blood cultures and a lumbar puncture were performed, and notably cloudy cerebrospinal fluid (CSF) was found; he was given dexamethasone, vancomycin, and ceftriaxone.

His past medical history included frequent ear infections (approximately 3 episodes annually) that required myringotomy tubes, sleep-disordered breathing that required tonsillectomy, and multiple febrile seizures. His immunizations were up to date. He was in the 65th percentile for height and 87th percentile for weight. His family history included no seizures, meningitis, or immunodeficiency. He lived in a semirural community in northern Colorado where his family raised chickens and cows, and he had not traveled.
