Where these two glands meet is called Rathke’s pouch. Previous Post. There is a notion that Rathke’s pouch proliferates to form the anterior pituitary lobe, from which PAs develop Reference Trifanescu, Stavrinides and Plaha 33; therefore, RCC derived from the remnants of Rathke’s pouch and PAs may have a shared origin. Eventually, it forms the anterior part of the pituitary gland called adenohypophysis. The symptoms depend upon which hormone is involved. Pituitary World News is a non-profit organization that seeks to increase awareness and reduce the number of undiagnosed and misdiagnosed people with a debilitating pituitary disease. In embryonic development, the anterior lobe of the pituitary gland develops from a saclike structure known as Rathke’s pouch. "Marsupialization" of the cyst, which means making a large opening at the bottom of the cyst, may prevent cyst recurrence in some cases.
