BACKGROUND: Pediatric brainstem abscesses are rare entities that account for 1% of all brain abscesses and, when diagnosed, constitute a neurosurgical emergency.
OBSERVATIONS: A previously healthy 11-year-old male presented with several days of worsening headache, confusion, and ataxia. Brain magnetic resonance imaging (MRI) revealed a midbrain and pons lesion. The patient subsequently had a rapid neurological decline with loss of consciousness and brainstem function. Follow-up MRI revealed significant enlargement of the brainstem lesion with extension into the pons, midbrain, and thalamus, with greater concerns for an abscess rather than a tumor or an inflammatory process. He was taken for an emergent stereotactic aspiration of the abscess, and broad-spectrum antibiotics were initiated. He had neurological improvement, which subsequently declined 5 days later with brain MRI revealing an increase in the brainstem abscess, which required a second stereotactic aspiration. After rehabilitation, he made a significant neurological recovery.
LESSONS: Pediatric brainstem abscesses are rare pathologies, and a high index of suspicion is needed in patients presenting with a brainstem lesion mimicking tumor but with rapid neurological decline despite no other evidence of infection or infectious/inflammatory markers. Stereotactic aspiration is required for large lesions to target the antibiotic treatment and as an adjunct to broad-spectrum antibiotics.
