BACKGROUND: Pediatric headache is a common cause of pediatric emergency department (ED) visits, and 8.8% of cases require imaging. Alarmingly, 12.5% of imaged cases have a pathologic cause. A pediatric patient with a complicated medical history presented to the pediatric ED with multiple cerebral abscesses. The possible causes and contributors to this rare cause of pediatric headache and a review of pediatric headache emergency management are presented.Case Presentation: A 12-year-old male patient with a complex medical and surgical history, including post-repair pulmonary valve stenosis, visited the pediatric ED for intractable and worsening left frontoparietal headache, refractory to ibuprofen, for 6 days. A physical examination revealed severe photophobia and restlessness secondary to severe head pain. Non-contrast brain computed tomography demonstrated two round, bilateral, parietal hypodense lesions with surrounding vasogenic edema. The lesions were consistent with abscesses on magnetic resonance imaging. Eventually, the patient underwent successful surgical abscess drainage and made a full recovery. The patient was lost to follow-up; therefore, no causative bacterial species was determined.
CONCLUSIONS: Managing pediatric headache in emergency settings requires a robust history and physical examination. Cerebral abscesses are an infrequent but fatal cause of pediatric headache and therefore should be considered among the differential diagnoses.

BACKGROUND: Resection of brain lesions associated with refractory epilepsy to achieve seizure control is well accepted. However, concurrent behavioral effects of these lesions such as changes in mood, personality, and cognition and the effects of surgery on behavior have not been well characterized. We describe 5 such children with epileptogenic lesions and significant behavioral abnormalities which improved after surgery.
METHODS: Five children (ages 3-14 years) with major behavioral abnormalities and lesional epilepsy were identified and treated at our center. Behavioral problems included academic impairment, impulsivity, self-injurious behavior, and decreased social interaction with diagnoses of ADHD, oppositional defiant disorder, and autism. Pre-operative neuropsychiatric testing was performed in 4/5 patients and revealed low-average cognitive and intellectual abilities for their age, attentional difficulties, and poor memory. Lesions were located in the temporal (2 gangliogliomas, 1 JPA, 1 cavernoma) and parietal (1 DNET) lobes. Gross total resection was achieved in all cases. At mean 1-year follow-up, seizure freedom (Engel 1a in 3 patients, Engel 1c in 2 patients) and significant behavioral improvements (academic performance, attention, socialization, and aggression) were achieved in all. Two patients manifested violence pre-operatively; one had extreme behavior with violence toward teachers and peers despite low seizure burden. Since surgery, his behavior has normalized.
CONCLUSIONS: We identified 5 patients with severe behavioral disorders in the setting of lesional epilepsy, all of whom demonstrated improvement after surgery. The degree of behavioral abnormality was disproportionate to epilepsy severity, suggesting a more complicated mechanism by which lesional epilepsy impacts behavior. We propose a novel paradigm in which lesionectomy may offer behavioral benefit even when seizures are not refractory. Thus, behavioral improvement may be an important novel goal for neurosurgical resection in children with epileptic brain lesions.
