There is a large sellar and predominantly suprasellar cyst characterised by thin walls and homogeneous content similar to the CSF signal.

Case Discussion

Final Diagnosis: Suprasellar cyst, resection: consistent with Rathke's cleft cyst.
Gross Description: The specimen is received in a single container labelled with the patient's demographics and SUPRASELLAR CYST. It consists of multiple fragments of thin translucent membranous tissue aggregating approximately to 0.8 cc in maximum volume.
Microscopic Description: Sections show fragments of a cyst wall lined by a continuous layer of benign cuboidal epithelium. In several fragments, normal anterior pituitary is intimately associated with the cyst wall. In other fragments, the cyst wall is supported by hypocellular fibrous connective tissue. The histologic appearance is consistent with Rathke's cleft cyst.
