Epidermoid cyst Epidermoid cyst. The other epithelial cells, which corresponded to stratified squamous cells blsa on light microscopy, had irregular nuclei, well developed endoplasmic reticulum, and numerous tonofibrils in the cytoplasm Fig.
Synonyms or Alternate Spellings: The anterior wall of the pouch gives rise to the anterior lobe of the pituitary pars distalis. Histological findings in symptomatic Rathke’s cleft cyst. This div only appears when the trigger link is hovered over.
Discussion Symptomatic Rathke’s cleft cyst is a rare clinical occurrence. Diabetes insipidus, diplopia, and dwarfism were also present in some cases. Note macrocyst MC formation arrows lined with epithelial cells due to collection of mucous-secreting and desquamative cells.
Craniopharyngioma Study An in vitro tissue culture study of a craniopharyngioma removed from a 4-year-old boy was done for comparison with the Rathke’s cleft cyst just described.
In Rathke’s cleft cyst mucous secretion and ciliated epithelium are seen, which are apparently absent in craniopharyngioma. The cyst wall was composed of three kinds of epithelial cells and a vascularized stroma of connective tissue. Electron microscopy of the present case showed the luminal surface of the non-ciliated cells to be coated by an electron-dense material. Arachnoid cyst Arachnoid cyst.
Persistence of this cleft with expansion is believed to be the origin of a Rathke’s cleft cyst.
Symptomatic Rathke’s cleft cyst
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. Use this site remotely Bookmark your favorite content Track your self-assessment progress and more!
Ciliary movement was noted not only on explanted cells, but also on some migrating cells. The cyst was studied by light and electron microscopy and by tissue culture; the findings are compared to those of a craniopharyngioma that was also studied with these techniques.

The diaphragma sellae was bulging out into the prechiasmatic region and both optic nerves were displaced laterally by a cystic mass with a whitish-gray appearance.
Similar material has also been demonstrated in respiratory epithelium. Visual disturbance includes deteriorated vision, visual field defect, and diplopia.
Case 1 Case 1. The primary presenting complaints of symptomatic Rathke’s cleft cyst were impairment of visual acuity and visual field defects, hypopituitarism, enlarged sella, and headache.
Check for errors rathkf try again. Microcyst formation was noted in the emigrating epithelial cells. Tissue Culture Study Surgical material was washed with buffer salt solution and cut into 0. In the columnar epithelium a group of cells with abundant cilia alternated with a group of goblet cells containing mucous secretions Fig.
Beneath this layer there were two to four layers of stratified squamous cells.
Case 12 Case About 3 ml of white mucous material was aspirated from it. This paper describes a patient with a symptomatic Rathke’s cleft cyst that was treated surgically. Visual acuity was impaired bilaterally due to a bitemporal hemianopsia.

Occasionally, however, they cause sellar enlargement, hypopituitarism, chiasmatic syndrome, and other neurological symptoms Table 1. Electron microscopy and tissue culture study of our case showed distinctively non-ciliated squamous, ciliated columnar and mucous-secreting cells. Pneumoencephalography showed an upward shift of the third ventricle with a filling defect of the prechiasmatic cistern.
Within this group of prickle cells, some were ciliated and some were mucous cells Fig. In our case, the mural nodule and cyst wall showed stratified squamous epithelium, in addition to ciliated and mucous-secreting cells.

In the cytoplasm, there were many bundles of tonofibrils and also electron-dense granules that were thought to be keratohyaline granules Fig. The histological findings in these 34 cases showed few variations. Case 2 Case 2. Case 10 Case There were no significant sex differences. Cases and figures Imaging differential diagnosis. Support Radiopaedia and see fewer ads. Light micrograph of cyst wall.
The suprasellar region was exposed. They also had numerous typical desmosomes. Articles Cases Courses Quiz. Goldzieher apparently described the first case in
