The inner lining was a single layer of columnar epithelium. Case 15 Case Case 14 Case In the columnar epithelium a group of cells with abundant cilia alternated with a group of goblet cells containing mucous secretions Fig. These squamous cells showed intercellular bridges between microvilli of adjacent cells.
The skin was dry and pale. Electron micrograph of ciliated cell and goblet cell on the medial surface of the cyst.
Our study suggests that both craniopharyngioma and Rathke’s cleft cyst have a common origin, remnants of Rathke’s pouch which is formed by the invagination rathks the stomodeumbut a different histological differentiation. In the cytoplasm, there were many bundles of tonofibrils and also electron-dense granules that were thought to be keratohyaline granules Fig.
The preoperative diagnosis was frequently that of chromophobe pituitary adenoma, because of the similarities in the clinical picture. Loading Stack – 0 images remaining. These symptoms usually lasted a week and recurred at monthly intervals.
The signal characteristics vary according to the cyst composition, which may be mucoid or serous. View All Subscription Options. After partial removal of the wall of the cyst and nodule, a silicone tube was inserted into the remaining cavity. You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

Diagnosis was made at autopsy in 15 cases and by surgical intervention and biopsy in 19 cases.
In this study ciliated epithelial and mucous-secreting cells in a pituitary which were also described by Rasmussen 20 were taken as pathognomonic for Rathke’s cleft cyst. A right frontal craniotomy was performed. Purely suprasellar location, although reported, is rare.
Rathke’s cleft cyst is generally thought to originate from the remnants of Rathke’s pouch, although some investigators 5, 28 have suggested that it has a neuroepithelial origin.
