Symptomatic Rathke’s cleft cyst

Histological findings in symptomatic Rathke’s cleft cyst. Ciliary movement bolxa noted not only on explanted cells, but also on some migrating cells. This was apparently the result of rahke of mucous material and desquamated cells. She was almost symptom-free for about 1 year, when she again developed headache, clouding of consciousness, and polydypsia.

In the columnar epithelium a group of cells with abundant cilia alternated with a group of goblet cells containing mucous secretions Fig. Please enter User Name. Diagnosis was made at autopsy in 15 cases and rthke surgical intervention and biopsy in 19 cases.

In the cytoplasm, there were many bundles of tonofibrils and also electron-dense granules that were thought to be keratohyaline granules Fig. Higher magnification of prickle cells with microvilli, desmosomes, and tonofibrils in outer layer of the cyst lumen.

In our case, the mural nodule and cyst wall showed stratified squamous epithelium, in addition to ciliated and mucous-secreting cells. In the cytoplasm of other cells, numerous tonofibrils were observed Fig.

At about 10 days after cultivation, macrocysts lined by epithelial cells gradually developed from the periphery of the explant Fig. Electron micrograph of day-old culture of a craniopharyngioma. They were all identified in vitro as prickle cells with microvilli and desmosomes. Epidermoid cyst Epidermoid cyst.

Case 15 Case 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.

Thank you rathkke updating your details. These cells alternated with the arthke cells. This intermediate form was non-ciliated squamous epithelium with a small amount of secretion in the cytoplasm. Cystic macroadenoma Cystic macroadenoma. Case 2 Case 2. Otherwise it is hidden from view. Case 11 Case The histological findings in these 34 cases showed few variations.

Diabetes insipidus, diplopia, and dwarfism were also present in some cases. In Rathke’s cleft cyst mucous secretion and ciliated epithelium are seen, which are apparently absent in craniopharyngioma. The anterior wall of the pouch gives rise to the anterior lobe of the pituitary pars distalis.

Log in Sign up. The wall of the cyst is typically lined by a single columnar cell layer of epithelium, often containing goblet rathkf, and is often ciliated.

The skin was dry and pale. Note ciliated cells and goblet cells lining a cyst. In the wall of the cyst, a small tumor nodule 3 to dr mm in diameter was found and removed with curettes. The lumen of the pouch narrows to form a cleft Rathke’s cleft that normally regresses.

Electron micrographs of ratkhe culture. Case 12 Case In general, however, craniopharyngioma is a suprasellar cystic tumor containing machine-oil-like fluid whereas Rathke’s cleft cyst is an intrasellar cyst containing white mucous fluid.

Electron microscopy of the cultured cells was carried out after fixation of day tissue culture explants with 2.

There is a recognised rzthke preponderance with a female to male ratio of approximately 2: The patient’s visual acuity and visual field defects improved considerably. Purely suprasellar location, although reported, is rare. Amenorrhea was noted after the first of these episodes.

Electron micrograph of the cyst nodule shows prickle cells with microvilli, desmosomes, numerous tonofibrils, and well developed endoplasmic reticulum. Although the underlying substrate is congenital, they appear to enlarge during life, as they are rare in childhood 2.
