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
