Abstract
BACKGROUND: Neonatal sonography of the brain is now an essential part of newborn care, particularly in high risk and unstable premature infants. Cranial ultrasound is the most available and easily repeatable imaging technique for the neonatal brain showing brain development and the most frequently occurring forms of cerebral injury in the preterm and terms. This study aims to assess the importance of cranial ultrasound as an investigatory modality for high-risk neonates and to find out the morphology of various cerebral lesions and correlate clinically. METHODOLOGY: An observational correlation clinical study was conducted at Sardar Patel Medical College, Bikaner involving 100 high-risk neonates admitted to Neonatal Intensive Care Unit (NICU) who was subjected to neurosonography on selected days as per protocol. Perinatal details were recorded, and clinical examination with appropriate investigations was done. The cranial ultrasound was done, and morphology of various findings was studied and recorded. Clinical correlation with cranial ultrasound findings and follow-up was done. RESULTS: On cranial ultrasound, 38% of neonates had abnormal findings. Twelve percent of these had evidence of intracranial bleed, 13% periventricular echogenicity, 7% had ventriculomegaly, 2% had cerebral edema, and 1% had leukomalacia. Three neonates had findings suggestive of simple cyst in middle cranial fossa, agenesis of corpus callosum, and choroid plexus cyst. CONCLUSIONS: Cranial ultrasonography is the best point of care neuroimaging method available for high-risk neonates. It is critical as an investigatory modality in NICU and effectively documents morphology of cerebral damage.
