Rathke cleft cyst is thought to arise from incomplete obliteration of the lumen of Rathke pouch. The cells of the anterior pituitary lobe, from which pituitary adenomas develop, are also derived from the cells of Rathke pouch. Although Rathke cleft cyst and pituitary adenoma have a shared ancestry, they rarely occur coincidentally. Rathke cleft cysts have been found incidentally in 11% 33% of p...

OBJECTIVE To highlight diagnostic and therapeutic issues about Rathke cleft cysts for otorhinolaryngologists. STUDY DESIGN Retrospective. METHODS We retrospectively reviewed data collected on Rathke cleft cysts between 1978 and 1998: presenting symptoms, visual acuity, surgical treatment, complications, recurrences, and effect on daily activity. RESULTS Twenty-nine patients were diagnosed...

The article describes changes in the structure, leaves, (including mesophyll structure of midrib, distribution stomata, and number vascular bundles) Malus during growing season (from June to August) under influence prolonged drought. leaves anatomy morphology were investigated by methods light scanning electron microscopy. study was carried out on four representatives genus Malus: M. niedzwetzk...

A 59-year-old man with confused mental status was admitted to our hospital. Laboratory reports showed him to have severe hyponatremia, and additional studies revealed panhypopituitarism. Brain magnetic resonance imaging showed a sellar cystic lesion, which consisted of a Rathke cleft cyst. Thus, the mass effect of the Rathke cleft cyst resulted in panhypopituitarism and finally induced euvolemi...

BACKGROUND AND PURPOSE Cystic pituitary adenomas may mimic Rathke cleft cysts when there is no solid enhancing component found on MR imaging, and preoperative differentiation may enable a more appropriate selection of treatment strategies. We investigated the diagnostic potential of MR imaging features to differentiate cystic pituitary adenomas from Rathke cleft cysts and to develop a diagnosti...

Background and Importance: Symptomatic Rathke’s cleft cyst is a rare lesion that often presents without any symptoms.  Case Presentation: We report a 40-year-old female with symptomatic Rathke’s cleft cyst located in the sellar and suprasellar region. She presented with visual disturbance, headache, weight gain, hypothyroidism and amenorrhea. The patient underwent surgery and ...

The preoperative diagnosis for an unusual skull base lesion was chordoma. The combination of imaging, pathologic, and surgical findings suggests the diagnosis of Rathke cyst.

Figure 1-MRI, sagittal SE 600/20. Intrasellar hypointense mass extending into sphenoid sinus (arrow). Pituitary gland elevated, optic nerve not involved. A 48 year old woman had an MRI examination of the brain which confirmed the clinical diagnosis of multiple sclerosis. Incidentally, a cystic mass was noted in the sella turcica. A pharyngeal soft tissue mass containing cysts was also shown (Fi...

PURPOSE To describe the gadolinium-enhanced MR findings of Rathke cleft cyst correlate them with the surgical findings, and define those preoperative findings that differentiate this lesion from other sellar and juxtasellar tumors. METHODS We studied 18 patients who were diagnosed as having Rathke cleft cyst pathologically. These patients were imaged with T1- and T2-weighted coronal and sagit...

Rathke cleft cysts are remnants of the Rathke pouch. Most of them are asymptomatic, but sometimes they can grow enough to cause compression of structures within and/or close to the sella, thus eliciting symptoms such as visual disturbance, pituitary defects, and headache. Asymptomatic cysts can safely be followed up with serial imaging, while the standard treatment for symptomatic lesions is su...
