Ventricular dilation occurs with excess fluid in the embryologic ventricles during brain development, we make a comparative analysis of two case reports on a 23rd-week fetus and a 10-month-old neonate. Ultrasound findings related to horns and ventricular system through transfontanelle ultrasound (excluding any > 95<sup>th</sup> error margin and < 5<sup>th</sup> percentile) can be utilized for a specific diagnosis of ventricular dilation. Hydrocephalus is defined as the accumulation of excessive CSF resulting in dilation of the cerebrospinal compartment in the calvaria; which can be acquired or congenital in origin. Hydrocephalus can also be seen due to obstructed flow, faulty absorption, and overproduction of CSF (in the subarachnoid space) by a choroid plexus papilloma. The diameter of the anterior horn of the RT and LT (hydrocephalic) lateral ventricles measured 15.3mm and 14.1mm respectively, far above the threshold for normal (control) neonates / RT and LT (anterior) lateral ventricles averaging 2.40mm and 2.51mm. These documented findings indicate the excellent agreement between fetal brain sonography in the diagnosis of fetal ventriculomegaly (anterior horn/ 10.4mm) and dilation (combined 40.8mm). Mean Head Circumference (MHC) for neonatal hydrocephalus was 44.2cm far above the normal average of 36.7cm. When we assessed the clinical benchmark of 10mm or (>19mm) for the neonate ventricle, it was far above the normal range (greater than > 95<sup>th</sup> percentile value).</p>}, number={1}, journal={Nepal Journal of Neuroscience}, author={AFODUN, Adam Moyosore and Quadri, Khadijah Kofoworola and MASUD, Mustapha Akajewole and Sheu, Sulaiman Oluwadare and Franck, Katembo Sikakulya and Okeniran, Olatayo Segun and Malinga, Raymond Joseph and Wandabwa, Julius Namasake}, year={2022}, month={Mar.}, pages={59–65} }
