  • Abstract
  • Look Inside

We report a case of Rathke's cleft cyst in pituitary tumor. A 31-year-old woman admitted to our hospital complained of visual disturbance, headache, amenor-rhea and galactorrhea. Serum prolactin level was 3,060 ng/ml. By means of CT scan and MRI, we found sup-rasellar-extending tumor to have cystic component in the center of the tumor. Transsphenoidal surgery re-vealed grayish jelly-like content in the cyst.

Histologically tumor cells were composed of chro-mophobic, basophilic and eosinophilic cells.
