Signal intensities of the pituitary gland were measured on T1-weighted sagittal MR images of 25 patients younger than 20 years old. We found that the signal intensities in the eight patients who were 8 weeks old or younger were higher (shorter T1) than those in the 17 older patients. We also noted a difference in the signal intensities across the pituitary gland, the signal being higher in the ...

The pituitary gland, also known as hypophysis, is a small pea-sized gland about 1 cm in diameter and 0.5 to 1 gram in weight. The pituitary gland resides in a small bony cavity situated at the base of the brain, known as sella turcica, and a pituitary stalk (infundibulum) maintains a connection between the pituitary gland and hypothalamus. The secretion of hormones by the pituitary gland is und...

Direct visualization of the pituitary gland is now possible with computed tomography (CT). It is hoped that this method will enable earlier detection and / or accurate localization of pituitary microadenomas. After contrast administration, it appears that microadenomas can be of the density of intravascular blood , or of higher or lower density [1]. Other criteria have been proposed to evaluate...

The pituitary gland is crucially important in the function of the endocrine axis. So far, antenatal depiction of the pituitary gland was possible only using magnetic resonance imaging. We describe antenatal visualization of the pituitary gland using 2- and 3-dimensional sonography. The appearance of the gland on sonography seems to be superior compares to prenatal magnetic resonance imaging. In...

metastasis from breast cancer to other parts of the body is very common, but the spread of the tumor to pituitary gland, especially to infandibulum, is a rare presentation. at the time of pituitary metastasis, a majority of the patients have clinical and radiological evidence of the disease. it seems that the posterior area of the gland is the most common site of metastasis, probably due to hig...

We present the MR appearance of the sella turcica in three sibling dwarfs with combined pituitary hormone deficiency in which MR images revealed a peripheral curvilinear band of enhancement about the pituitary gland in all three patients, a normal-size pituitary gland in two siblings, a mildly enlarged pituitary gland in one sibling, and a thin infundibulum and a normal posterior pituitary brig...

Pituitary (hypophysis), the secreting gland located in the sella turcica, has fascinated the scientists since ages. In 1543 the Belgian scientist Andreas Vesalius described the anatomy of pituitary gland for the first time. He believed that pituitary produces mucus, which is secreted from the brain into the nasal cavity. This is why pituitary was called the mucous gland (glandula pituitaria; pi...

Duplication of the pituitary gland is a rare malformation. The authors describe a patient with features of the median cleft face syndrome (hypertelorism, V-shaped hairline, and developmental delay) who exhibited duplication of the pituitary gland and diffuse thickening of the hypothalamus (hypothalamic hamartoma) as shown by MR. The embryology of the developing pituitary gland and pathogenesis ...
