A Rathke's cleft cyst is thought to come from the remains of the Rathke’s pouch. In a large study series involving 782 patients with known PA, the rate of concomitant RCC was 0.51%. This pouch normally closes early in fetal development, but a remnant often persists as a cleft that lies within the pituitary gland. Rathke’s cleft cyst is a benign (not cancer), fluid-filled growth that usually develops between the two lobes of the pituitary gland at the base of the brain. Canonical WNT Signaling Regulates the Pituitary Organizer and Pituitary Gland Formation "The pituitary organizer is a domain within the ventral diencephalon that expresses Bmp4, Fgf8, and Fgf10, which induce the formation of the pituitary precursor, Rathke's pouch, from the oral ectoderm. The place where the anterior and posterior glands meet is called Rathke's pouch. craniobuccal pouch (craniopharyngeal pouch) Rathke's pouch. Doctors think this occurs because of compression of the pituitary stalk, the connection between the pituitary gland and the brain. abdominovesical pouch the pouchlike reflection of the peritoneum from the abdominal wall to the anterior surface of the bladder. Vision loss. Problems may occur when the cyst grows larger from the continual accumulation of fluid and presses on the nerves and structures around it. Rathke's cleft cyst is an abnormal fluid-filled (cyst) sac that usually is found between the anterior and posterior pituitary glands. Occasionally, this remnant gives rise to a large cyst, called Rathkes cleft cyst (RCC), that causes symptoms. During embryonic development, the Rathke pouch forms as a depression in the roof of the mouth, eventually losing its connection to the pharynx and giving rise to the anterior pituitary gland. As a fetus develops: The place where the anterior and posterior glands meet is called Rathke's pouch. This pouch normally closes in fetal development, but a remnant often persists as a cleft that lies between the anterior and posterior lobes of the pituitary gland. They can occur at any age, although most are identified in adults. Aims: To determine the differential magnetic resonance imaging (MRI) features of pituitary adenoma, craniopharyngioma, and Rathke cleft cyst involving both intrasellar and suprasellar regions. The pituitary gland sits in a little saddle shaped spot, known as the “sella turcica” at the base of the skull. Reduction of sex hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). "Marsupialization" of the cyst, which means making a large opening at the bottom of the cyst, may prevent cyst recurrence in some cases. If instead of regressing the cleft persists and enlarges, it may form into a Rathke's cleft cyst. Compression of the optic nerves may lead to visual deficits, usually a bitemporal hemianopsia. This pouch normally closes early in fetal development, but a remnant often persists as a cleft that lies within the pituitary gland. If left over after development, the cyst can slowly expand and eventually cause symptoms. As development proceeds in the womb, the hollow center of the Rathke’s pouch shrinks to a narrow trough called a cleft. In a large study series involving 782 patients with known PA, the rate of concomitant RCC was 0.51%. Then the anterior pouch wall thickens to form the anterior pituitary lobe.

Eventually, it forms the anterior part of the pituitary gland called adenohypophysis. Occasionally, your doctor may order a computed tomography (CT) scans of the brain, though it is less reliable than an MRI scan.In order to confirm a diagnosis of Rathke's cleft cyst, your doctor will need to rule out other possible conditions that present with a pituitary cyst: If your symptoms suggest pituitary failure (hypopituitarism), your doctor will order a complete evaluation of the endocrine system. In embryogenesis, Rathke's pouch is an evagination at the roof of the developing mouth in front of the buccopharyngeal membrane. During the process of embryogenesis, Rathke’s pouch is formed at the roof of the mouth of the embryo. It is thought to be a remnant of an embryologic structure called Rathke's pouch, hence the name.
