The authors were presented with a term female neonate with a large occipital mass, who was already being treated for neonatal pneumonia at another hospital. On assessment, apart from the mass, the patient presented with an unremarkable systemic and neurological physical examination. She underwent repair of the occipital mass, which was complicated by nosocomial ventriculitis. However, the patient was discharged well after completing antibiotic treatment. On regular outpatient follow-ups, the patient presented with a good cry, suck, and activity. There have been no reports of seizures, decrease in sensorium, aspiration episodes, stridor or any other complaints, apart from poor head and sitting control. The workup also showed profound bilateral hearing loss. Despite these complications, the patient currently exhibits good visual and social development. This is attributed to timely intervention as well as the minimal amount of herniated cerebellar tissue that the patient presented with, highlighting the individualised management and outcomes for cases of Chiari malformation type III.
