Adamantinomatous craniopharyngiomas is the most common form (90%),  and typically have a lobulated contour as a result of usually multiple cystic lesions. Solid components are present, but usually form a relatively minor component of the mass, and enhance vividly on CT scans. The calcification is very common (90%). These tumor have a predilection to be large, extending superiorly into the third ventricle, and encasing vessels, and even being adherent to adjacent structures.

Overview

CT

Although similar in terms of location, radiographic features depend on the type, although due to a significant minority of tumor having both adamantinomatous and papillary components many show overlapping features.[1]

Adamantinomatous

Adamantinomatous craniopharyngiomas is the most common form (90%), and typically have a lobulated contour as a result of usually multiple cystic lesions. Solid components are present, but usually form a relatively minor component of the mass, and enhance vividly on CT scans. The calcification is very common (90%). These tumor have a predilection to be large, extending superiorly into the third ventricle, and encasing vessels, and even being adherent to adjacent structures. The findings on the CT are:

  • Cysts
    • Typically large and a dominant feature
    • Near CSF density
  • Solid component
    • Soft tissue density
    • Enhancement in 90%
  • Calcification
    • Seen in 90%
    • Typically stippled and often peripheral in location
