Papillary craniopharyngioma diagnosis
Papillary craniopharyngiomas tend to be more spherical in outline and usually lack the prominent cystic component; most are either solid or contain a few smaller cysts. Calcification is uncommon or even rare in the papillary subtype, a fact often forgotten.
These tumors tend to displace adjacent structures.
MRI
cysts when present, they are variable in signal T1: 85% are T1 hypointense 4 solid component T1: iso- to slightly hypointense to brain T1 C+ (Gd): vivid enhancement T2: variable/mixed MR spectroscopy: cyst contents does not show a broad lipid spectrum as they are filled with aqueous fluid
