Abstract

Two rare cases of entirely suprasellar Rathke's cleft cyst were reported.

Case 1. A 62-year-old man was admitted to our hos-pital on the 14th of January, 1988, complaining of headache and diplopia.

A plain skull x-ray showed the sella turicica was nor-mal. CT scan and MRI demonstrated a lesion mass lo-cated entirely in the suprasellar cistern. Right fronto-temporal craniotomy was performed, and the cyst wall was resected subtotally. Microscopic sections of cyst wall showed ciliated single layer with focal stratified epithelium.

Case 2. A 51-year-old man was hospitalised complain-ing of visual impairment in the left eye. Endocrinologi-cal examination showed no abnormalities. CT and MRI demnostrated a lesion mass located entirely in the su-prasellar region. Right frontotemporal craniotomy was performed. The mass was opened and a large amount of yellowish fluid was released.

Histologically, the specimens were simple ciliated cuboidal epihelium. Postoperative courses of these pa-tients were uneventful. The findings on CT and MRI of the cases located entirely in the suprasellar region were varied. The histopathogenesis and embryological pathogenesis of Rathke's cleft cyst in the literature, particularly the entirely suprasellar type, were dis-cussed.
