Seessel's pouch an outpouching of the embryonic pharynx rostrad to the pharyngeal membrane and caudal to 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. At Pacific Pituitary Disorders Program, we have one of the world’s largest experiences in transsphenoidal endoscopic endonasal surgery. Attempts to remove the cyst lining should be avoided because this can result in pituitary gland damage. Based on the specific nature of the patient's Rathke's cleft cyst, treatment may require surgical drainage and/or removal. Fortunately, there have been major technical advances in this surgical approach over the last two decades, including use of high-definition endoscopy, surgical navigation techniques and more effective skull base closure methods. Debi Dear Debi, Rathkes pouch cyst is also know an a hypophysial duct tumor and fall under the subtype of craniopharyngioma. During ontogeny, part of Rathke’s pouch, a physiologically superior pouching of the stomodeal ectoderm, may remain, forming the usual anomaly known as Rathke’s cleft cyst. A complete pituitary hormonal blood evaluation should also be performed. Schedule a consultation or record review via phone or online.

These cysts are found during routine autopsies in 13% to 22% of cases (1). The incidence of RCCs is much lower in the pediatric population; however, symptoms, imaging findings, and outcomes are similar, suggesting that pediatric RCCs arise from growth of remnants of the embryonic Rathke pouch earlier in life than adult RCCs but … However, for patients with a symptomatic (and typically larger) Rathke’s cleft cyst, endoscopic endonasal surgical removal (via the nose) is the treatment of choice. If symptomatic: Rathke's cleft cyst is a developmental remnant of rathke pouch, a normal structure formed during development of the pituitary gland.

Tooth enamel like calcification is seen. The difference is that craniopharyngiomas grow by cell division and fluid accumulation, whereas Rathke's cleft cysts grow only by fluid accumulation. Rathke's cyst, or Rathke cleft cyst (RCC), is a benign epithelium-lined cyst, that arises primarily within the sella turcica and is thought to originate from remnants of the Rathke's pouch (Rathke's pouch is the primordium of the anterior and intermediate lobes of the pituitary gland). The majority of the tumors occur in children but it is not uncommon in adults. Most of these cysts are: In some instances, continual accumulation of fluid may cause the cyst to grow.
