“…The earlier onset of puberty in girls, as compared to boys, may be at the root of the sex difference in pituitary volume noted here. Indeed, growth spurts have been noted in previous reports that may result form pubertal changes (Hayakawa et al, 1989;Elster et al, 1990;Argyropoulou et al, 1991;Takano et al, 1999). This spurt, by occurring in females prior to males, may lead to a temporary difference in volume between the sexes.…”

Development and sexual dimorphism of the pituitary gland

The pituitary gland plays a central role in sexual development and brain function. Therefore, we examined the effect of age and gender on pituitary volume in a large sample of healthy children and adults. Volumetric magnetic resonance imaging (MRI) was conducted in one hundred and fifty four (77 males and 77 females) healthy participants. Males were between the ages of 7 to 35 years (16.91 ± 5.89 years) and females were 7 to 35 years of age (16.75 ± 5.75 years). Subjects were divided into subgroups of age (7 to 9, 10 to 13, 14 to 17, 18 to 21, 22 and older) and sex (male/female). Pituitary gland volume differed between sexes when comparing the age groups (F = 3.55, df = 2, 143, p = 0.03). Females demonstrated larger pituitary glands than males in the age 14 to 17 year old groups (p = 0.04). Young (19 years and under) and old (20 years and older) females demonstrated a correlation between pituitary volume and age. Males did not show this relationship. These findings provide additional evidence for gender differences in the normative anatomy of the pituitary and may have relevance for the study of various childhood onset neuropsychiatric disorders in which pituitary dysfunction has been implicated.

“…Using sagittal MRI scans Hayakawa et al, (1989) examined the pituitary gland in 150 subjects (newborn to 60 years of age; 87 males and 63 females). A growth spurt was noted in the 10 -15 year olds and decline in volume in the 51 -60 year olds.…”

“…It is generally accepted that the size and shape of the corpus callosum are sensitive indicators of the volume of the white matter and its myelination status. 13,14 In addition, in sonography studies regarding very premature infants, the length of the corpus callosum at term equivalency was significantly shorter than that in control infants, and the growth rate of corpus callosal length has significant correlation with clinical outcome. 15,16 We then consider that the length of the corpus callosum, as well as its size and shape, reflects the volume of the myelinated white matter.…”

“…Similarly, a study in which dimensions of the cerebellar vermis were measured reported a marked increase in cerebellar vermis size between the ages of 0 and 1. 32 One study performed with volume measurement paralleled our own research finding by determining rapid growth in cerebellar volume in the first year of life. 17 The difference in cerebellar size between the sexes is unclear in the literature, and conflicting opinions exist.…”

“…One study measuring cerebellar vermis dimensions assessed vermis size in individuals aged 0-60 years, but no mean vermis dimensions were given for the 0-4 age group. 32 Another study measured cerebral and cerebellar volumes at MRI in children aged 4-18 years and determined no change in volumes in this age group. 18 Our research therefore involved the 0-4 age group, in which we predicted a possible change in cerebellar dimensions, and these were observed to increase up to the age of 4 years.…”

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.
