“…The primary fissure of the vermis could normally be seen on MRI at approximately 25 to 26 weeks' gestation in the sagittal plane according to Adamsbaum et al 5 and even as late as 30 weeks in another MRI study. 7 Although on 2-dimensional (2D) ultrasonographic evaluation, the primary fissure can be shown from 22 to 23 weeks and onward ( Figure 2B) or even at 27 weeks, 4 our 3D study confirms the normality of the vermis by showing the primary fissure as early as 18 weeks (in ≈40% of cases), in more than 90% at 22 weeks, and in 100% of cases from 23 to 24 weeks and onward.…”

“…6 The cerebellum, including the cerebellar hemispheres, the superior and inferior vermis, the fourth ventricle, and the cisterna magna, can be shown easily. Using a transvaginal transducer, Malinger et al 4 examined the appearance and development of the fetal cerebellar vermis in 101 fetuses between 21 and 39 weeks' gestation. They successfully visualized the vermis in 96% of the cases.…”

Objective. The purpose of this study was to establish the normality of the fetal vermis, ie, the time of appearance of the primary fissure, as well as its measurements between 18 and 26 weeks' gestation, using 3-dimensional (3D) ultrasonography. Methods. A prospective cross-sectional study of normal singleton pregnancies was conducted. Examinations were performed with high-resolution transabdominal ultrasonography using the axial plane in 173 fetuses between 18 and 26 weeks' gestation. Postprocessing measurements of the fetal vermis were done with 4-dimensional software using static volume contrast imaging and tomographic ultrasound imaging in the C-plane. Detection of the primary fissure was evaluated in all cases, and the time of appearance was documented. Results. Adequate vermis measurements were obtained in 173 fetuses. Vermian length as a function of gestational age was expressed by regression equations, and the correlation coefficients were found to be highly statistically significant (P < .001). The normal mean ± 2 SD for each gestational week was defined. The primary fissure was observed at 24 weeks' gestation in all cases, at 22 weeks in 94% of cases, and as early as 18 weeks in 40%. Conclusions. This 3D study documents the appearance of the primary fissure and presents the normal range of vermian measurements, confirming normal development of the fetal vermis starting as early as 18 weeks' gestation. It also shows an easy method for visualizing the vermis with 3D ultrasonography at every gestational week regardless of fetal presentation.

A AB BS S T TR RA AC CT T O Ob bj je ec ct ti iv ve e: : Several diseases progress with cerebellar atrophy and hypoplasia. Cerebellum dimension measurements facilitating the assessment of decreases in cerebellum size on radiological images between the ages of 0 and 4 years in particular, when the cerebellum is still growing, will be of considerable use in clinical practice and appropriate for measurement value standardization. This will allow easier interpretetation of findings, together with more accurate diagnosis or a decrease in delays caused by false diagnosis. This study, the purpose of which was to obtain a database suitable for clinical use by performing cerebellar development dimension measurements in normal individuals aged 0-4 years, investigated the effect on cerebellar dimensions of parameters such as height, weight, head circumference and birth week. M Ma at te er ri ia al l a an nd d M Me et th ho od ds s: : One hundred fourty children aged 0-4 years, 56 girls and 84 boys, undergoing magnetic resonance imaging of the brain at the Karadeniz Technical University Farabi Hospital Radiology Department with no structural cerebral or cerebellar abnormalities were included in the study. R Re es su ul lt ts s: : In this study of cerebellar dimensions in healthy children, these were positively correlated with weight, head circumference and height in both genders. Preterm birth had a significant effect on cerebellar dimensions. C Co on nc cl lu us si io on n: : In conclusion, this scale developed by measuring the cerebellar dimensions of healthy children aged 0-4 years will be of considerable practical assistance in terms of assessing measurements performed in a clinical environment. K Ke ey y W Wo or rd ds s: : Magnetic resonance imaging; child Ö ÖZ ZE ET T A Am ma aç ç: : Serebellumun atrofisi ve hipoplazisi ile giden birçok hastalık mevcuttur. Özellikle serebellumun büyümeye devam ettiği 0-4 yaş arasında radyolojik görüntülerde serebellum boyutlarındaki azalmanın değerlendirilebilmesi için serebellum boyutlarının ölçümleri, klinikte pratik olarak yararlı olacak ve ölçüm değerlerinin standardizasyonu için uygun olacaktır. Böylece bulguların daha kolay tanımlanabileceği ve doğru tanı konulamaması ya da tanı konulmasındaki gecikmelerin azalacağı öngörülmektedir. Bu nedenle 0-4 yaş arası normal bireylerde serebellum gelişimi boyut ölçümleri ile yaparak klinik kullanıma uygun bir veri dökümü elde etmeyi amaçladığımız bu çalışmada boy, kilo, baş çevresi, doğum haftası gibi parametrelerin serebellum boyutları üzerine etkilerini de değerlendirdik.

“…También se pueden ver el cavum vergae y el cavum veli interpositi, el tallo cerebral, la fosa posterior y el diámetro anteroposterior de la protuberancia (69). En este plano será donde también se debe medir la altura del vermis desde la porción más craneal del culmen hasta la porción más caudal de la úvula (70). Así pues, en este plano también se identifican: el diámetro anteroposterior del vérmix, el área y la circunferencia del vérmix.…”
