“…Measurements at the foramen monro level accepted the upper limit for lateral ventricular width as 10 mm (13). In this study, frontal horn VW is between 1.48 and 2.56 mm in prematurity and between 2.98 and 3.92 mm in mature, similar to the literature.…”

Aim: We aimed to measure the subarachnoid space and ventricular width with transfontanel sonography in premature and mature newborns and to identify the subarachnoid space/ventricular width ratio. Material and method: This prospective study included 123 premature and 121 mature newborns, totally 244 cases. All cases had sonographic investigation from the anterior fontanel with 4.8-11.0 MHz linear transducer. The subarachnoid space/ventricular width ratio was calculated. Analysis of variables was completed with SPSS 22.0 program; and independent samples T test was used for the comparisons between the groups. Results: The birth week, head circumference, weight and height values of mature newborns were higher compared to the premature newborns (p<0.001, for each). The subarachnoid space and ventricular width values for mature and premature newborns were 3.13±0.39 mm, 1.79±0.45 mm, and 3.45±0.47 mm and 2.02±0.54 mm, respectively (p<0.001, for each). The subarachnoid space/ventricular width ratios were 0.90±0.02 and 0.89±0.05 in mature and premature newborns with no difference identified between the groups (p=0.432). The result of Receiver Operating Curve analysis was that the threshold values for premature-mature distinction were 2.29 mm for subarachnoid space and 2.49 mm for ventricular width; and the sensitivity and specificity for both values were found to be 100% (p<0.001, for each). Conclusion: Subarachnoid space and ventricular width values vary according to the birth week of newborns, though the subarachnoid space/ventricular width ratio is not different. Transfontanel sonography is a useful imaging method for measurement of cerebrospinal fluid spaces in newborns.

“…Sabouri et al [14] reported that mean values for SAS was 1-4 mm and for VW was 4.5-8 mm. Width of lateral ventricle is accepted as normal if it is smaller than 10 mm at the level of Monro's foramen [7]. In our study, mean SAS and VW measurements were found as 3.1 (0.5-6) mm and 3.6 (1.3-5) mm, respectively.…”

“…By 21 wk the upper limit of normal is below 50%. It appears that in early congenital hydrocephalus the occipital horns dilate prior to enlargement of the bodies of the lateral ventricles (8). We have observed 2 such cases; the bodies of the lateral ventricles were within the normal range, but the occipital horns were dilated (Fig.…”

Improvements in ultrasound technology have now made possible detailed visualization of fetal intracranial anatomy. Structures such as the midbrain, thalami, and lateral ventricles can be routinely imaged. Measurements of the ratio between lateral ventricular width and cerebral hemispheric width demonstrate a steady decrease from a mean of 56% at 15 wk gestation to 28% at term reflecting the relatively more rapid growth of the cerebral hemispheres as compared with the cerebral ventricles. Application of this new ultrasound data greatly facilitates accurate and consistent biparietal diameter estimations and early diagnosis of fetal hydrocephalus and other fetal cranial anomalies. This article describes the axial fetal cranial anatomy as demonstrated sonically and includes a table for normal fetal ventricular size at various gestational ages, based on evaluation of 196 normal fetuses. Some of the more common fetal cranial anomalies amenable to ultrasound diagnosis in utero are discussed.
