Page created on April 4, 2019. Not updated since.

There is a cystic tumor which is encapsulated. The tumor is filled with a greyish liquid material, which is a remnant of cystic degeneration. There are small papillary structures on the inside of the tumor.

Diagnosis: Craniopharyngeoma

Risk factors:

  • Nothing special.


This tumor originates from the Rathke pouch, which normally develops into the pituitary and thyroid glands. Craniopharyngeomas commonly occur between the corpus callosum and brainstem, in the suprasellar region. Here they may compress the pituitary and/or optic nerve, causing hypopituitarism and/or visual defects, respectively.
