The aim of this study was to ascertain the prevalence and type of incidental findings present in the low risk term brain using MRI. Out of 200 infants, 105 had incidental findings, with 8 requiring follow-up assessment. Common findings included subdural haemorrhage, punctate and cystic lesions and hyperintense signal of the basal ganglia. Findings requiring further assessment included subarachnoid, cerebellar, and germinal matrix haemorrhages, ectopic posterior pituitary lobe, subepenymal heterotopia and venous infarcts. Prevalence of incidental findings in this cohort is significant. Communicating to parents the possibility of detecting abnormalities and referral pathways are important considerations in neonatal research.
