Curr Trends Clin Med Imaging 1(3): CTCMI.MS.ID.55563 (2017) Introduction The pituitary gland is located in pituitary fossa within sphenoid bone The size and shape of the normal pituitary gland varies. In adult males the gland ranges from 8-10 mm craniocaudad dimension in the sagittal plane. The upper contour of the gland is normally flat or concave. In females, the size of the gland varies with the menstrual cycle and pregnancy The pea-sized pituitary gland is composed of both anterior and posterior lobes; in adults, the vertical diameter is approximately 8mm, with the horizontal circumference found to be 12 millimeters (mm). 1  These are encased in a tough membrane (dura), and just beneath another such membrane, the sellar diaphragm, which has an opening to allow a structure called the infundibular stalk to exit the gland Growth hormone in aquaculture: The teleost growth hormone (GH), which is produced by the pituitary, is an example of a hormone with many actions, as illustrated in Fig. 1.24 (Bone and Moore, 2008).The GH gene has been used by Aquabounty Technologies Inc. to produce genetically modified (GM) Atlantic salmon with superior growth characteristics (referred to as AquAdvantage salmon) The pituitary gland is called the Master Gland because it directs a multitude of endocrine functions in the body.It regulates hormone activity in other endocrine glands and organs. Pituitary activity is regulated by hormones of the hypothalamus, a brain region connected to the pituitary by the pituitary stalk.; The pituitary is composed of an anterior and posterior lobe with an intermediate.

Pituitary Gland and Pituitary Tumor

The pituitary gland is NOT in the brain and pituitary tissue is different from brain tissue. Since the pituitary gland is located at the base of the brain and is connected to the brain by a thin stalk, there is often confusion, particularly by insurance companies, about the classification of a pituitary tumor. A pituitary tumor is NOT a brain. Biopsy specimens showed the morphologic characteristics of a normal, nonhyperplastic pituitary gland. All seven women were seen at yearly intervals for 2-8 yr (median, 4 yr). Clinical and hormonal status remained stable, as did the structure and size of pituitary, on serial MRI Alternative names for empty sella syndrome. ESS. What is empty sella syndrome? The pituitary gland sits in the sella turcica, a bony cup at the base of the brain, which protects it. On magnetic resonance imaging scans of a normal brain, the pituitary gland would normally almost fill the sella turcica.. Empty sella syndrome is a condition where the pituitary gland appears flattened or shrunken. The pituitary gland is at the base of the brain right between the optic nerves. Also called the 'master gland', this pea-sized gland controls hormone functions throughout the body. Any problem with this gland can make you deal with all sorts of health problems The pituitary gland sits within the sella turcica which is a cup shaped depression in the sphenoid bone. The sphenoid air sinus lies below and anterior to the sella turcica (Fig. 1).Lying above the pituitary gland is a CSF space, the suprasellar system, which contains the optic chiasm (Fig. 1 A and B).The lateral walls of the pituitary fossa are formed by the cavernous sinuses (Fig. 1 B) which.

Cranial magnetic resonance (MR) imaging was performed in 38 pregnant and postpartum women and 30 nonpregnant age-matched control subjects to establish standards for pituitary gland size and shape during this period. Gland height and infundibulum width were measured on midline T1-weighted sagittal images. Gland convexity or concavity was graded.

The human Pituitary gland is reddish- Grey, an oval structure about 10mm in diameter in the brain just behind the optic chiasma as an extension of the field of the hypothalamus.

The height, shape and size of an individual is greatly influenced by the activity of pituitary gland Enlargement of the pituitary gland is when a normal pituitary gland becomes bigger in size for some reason. The change in size can cause your pituitary gland to make too much or too little of certain hormones. A large pituitary may also push on the nerves that connect your eyes to your brain and cause vision problems The pituitary gland is a pea-sized oval structure, suspended from the underside of the brain by the pituitary stalk (known as the infundibulum).

pituitary tumor is pituitary adenoma — adeno means gland, oma means tumor. Most pituitary adenomas develop in the front two-thirds of the pituitary gland. That area is called the adenohypophysis, or the anterior pituitary. Pituitary tumors rarely develop in the rear one-third of the pituitary gland, calle Hyperpituitarism is defined as an excessive secretion or production of 1 or more of the hormones produced by the pituitary gland 1). The pituitary gland produces and secretes various hormones that play a vital role in regulating endocrine function within the body. The pituitary gland consists of 2 lobes: an anterior and a posterior lobe

Surgical removal of a pituitary tumor usually is necessary if the tumor is pressing on the optic nerves or if the tumor is overproducing certain hormones. The success of surgery depends on the tumor type, its location, its size and whether the tumor has invaded surrounding tissues. The two main surgical techniques for treating pituitary tumors are MRI Imaging. One method we use to detect Rathke's cleft cysts is a magnetic resonance imaging (MRI) of the pituitary gland. We use a special MRI pituitary protocol in order to best visualize the tumor. Occasionally, your doctor may order a computed tomography (CT) scans of the brain, though it is less reliable than an MRI scan

From its lofty position above the rest of the body it sends signals to the thyroid gland, adrenal glands, ovaries and testes, directing them to produce thyroid hormone, cortisol, estrogen, testosterone, and many more

The pituitary gland is a reddish, small, rounded or oval, unpaired structure about the size of a large pea. It weighs 0.5 to 0.6 gm in adult human beings. In women it is larger in size. Pituitary gland continues to grow upto the age of forty years, but later starts to decrease in size. In pregnant females, it is usually larger Estrogens produced by the placenta stimulate the pituitary gland to nearly double in size. Most of that increase in size is related to hyperplasia of the prolactin producing cells. Physiologically, this readies the pregnant woman to breast-feed her child. Birth control pills are another common cause of hyperplasia of the prolactin producing cells

The pituitary is located within the pituitary fossa of the sphenoid bone, anterior to the lamina terminalis and superior to the pharynx. The shape of the bone surrounding the pituitary led to the naming sella turcica (Latin sella = saddle, turcica = Turkish), as it resembled a saddle shape.. Maternal pituitary also increases in size during pregnancy, due mainly to hyperplasia of the prolactin. Pituitary disorders occur when your pituitary gland fails to function as it normally should, likely because of a tumor, which is an abnormal growth of cells. Expert endocrinologists determined that about one in five people will get a tumor in their pituitary gland (16% to 20% of the population) The size and location of the residual tumor are the limiting factors in selecting a patient for this treatment. It can be used in cases where the entire tumor was not successfully removed. Gamma Knife radiation is focused at the residual tumor. If the tumor is not seen on the MRI scan the entire pituitary gland is usually targeted for treatment It is a small-sized gland with master functions; hence, its size and morphology have been a source of interest for many researchers. Sometimes in imaging, one takes a quick look at the contour of the superior surface of the pituitary gland or the size of the sella turcica as an indication or suggestion of enlargement of the gland
