Adamantinomatous craniopharyngioma

Discussion:

Adamantinomatous craniopharyngiomas​ typically involve the sella and suprasellar space. Some craniopharyingiomas can be both intrasellar and suprasellar, having a "snowman" appearance.

Description of MRI findings:

  • cystic area which is hyperintense on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images with heterogeneous isointense to hypointense solid components in the caudal part. 
  • signal intensity varies on T1-weighted images. The cystic contents can appear hyperintense if they have a high protein, blood product, and/or cholesterol content. In this case the cystic component is T1-isointense.
  • contrast enhancement is seen, which is characteristic. 
  • compression of the third ventricle may occur and hydrocephalus may be present. Such compression helps in distinguishing craniopharyngioma from Rathke's cleft cyst or pituitary adenoma.
