A 4-month-old boy was brought to the hospital actively seizing. He was euglycemic. Postseizure control, he was intubated for altered sensorium and poor respiratory efforts. Circulation was maintained. The infant was febrile, and history revealed high-grade, fever for a week, followed by multiple seizures for 3 days (brief up rolling of eyeballs) without loss of consciousness in between. There was no preceding trauma, ear discharge, and respiratory, gastrointestinal, or urinary symptoms. The infant was the first issue of non-related parents, born at term with normal birth weight. There was no significant past, antenatal, perinatal, or family history. The child was breast fed for the initial 3 months. Currently, he was being bottle-fed with diluted cow's milk. He was immunized and development was age appropriate.
His anthropometric measurements were normal. Cranium, sutures, fontanelle, and spine were unremarkable. Neurocutaneous markers and dysmorphic features were absent. The only salient examination findings was firm hepatosplenomegaly (liver span 6.5 cm and spleen 2 cm below costal margin). No cranial/focal neurological deficits or tone abnormalities were identified. The clinical diagnosis was acute febrile encephalopathy. Blood counts revealed hemoglobin 10.3 g/dL, white blood count 24 × 103/μL (80% neutrophils and 20% lymphocytes), and platelet count 330 × 103/μL. Serum electrolytes were normal. Cerebrospinal fluid (CSF) was grossly turbid with 200 leukocytes/mm3 (all neutrophils), hypoglycorrhachia (CSF glucose 35 mg/dL, blood glucose 118 mg/dL), and elevated protein (200 mg/dL). Blood and CSF cultures grew Salmonella enterica subspecies enteritidis, sensitive to ciprofloxacin and ceftriaxone. Despite antibiotics and multiple antiepileptics, seizures persisted, and he developed signs of increased intracranial pressure. Plain and contrast-enhanced computed tomography showed multiple brain abscess [Figure 1]. Intravenous antibiotics continued for 6 weeks. There was no indication for surgical intervention: fever abated; seizures ceased; sensorium improved; he was extubated, discharged, and kept under follow-up. Primary and secondary immunodeficiencies were excluded. After 6 months, serial head circumference monitoring demonstrates normal growth trajectory, whereas hearing assessment and neurodevelopmental status are normal.

Salmonella neuroinfection is uncommon in infants. This includes meningitis, subdural/epidural empyema, ventriculitis, venous infarcts, cerebritis,,, and intracranial abscesses (100 case reports found). The clinical presentation of abscesses comprises of fever (~100%), seizures (75%), altered sensorium (60%), and focal deficits (40%). High-risk factors include immunodeficiency states, asymptomatic carrier caregivers, and contaminated feeds. Diagnosis is established by the clinical phenotype, neuroimaging, and cultures. The primary management is prolonged antibiotic therapy. The surgical intervention including drainage of abscess and/or subdural effusion, or placement of ventriculoperitoneal shunt, is individualized. Salmonella meningitis has high likelihood of morbidity, acute complications, and neurological sequelae (epilepsy, visual/hearing impairment, locomotor disability, etc.). Early recognition is associated with better prognosis.
