Overview
MRI
The MRI findings depends on the type of craniopharyngioma.[1]
Adamantinomatous
The findings on MRI are:
- Cysts
- Variable but 80% are mostly or partly T2 hyperintense
- T1: iso- to hyperintense to brain (due to high protein content machinery oil cysts)
- Solid component
- T1 C+ (Gd): vivid enhancement
- T2: variable or mixed
- Calcification
- Difficult to appreciate on conventional imaging
- Susceptible sequences may better demonstrate calcification
MR angiography: It may demonstrate displacement of the A1 segment of the anterior cerebral artery (ACA).
MR spectroscopy: Cyst contents may show a broad lipid spectrum, with an otherwise flat baseline.
Papillary
The findings on MRI are:
- Cysts
- When present they are variable in signal
- 85% T1 hypointense
- Solid component
- T1: iso- to lightly hypointense to brain
- T1 C+: vivid enhancement
- T2: variable/mixed
MR spectroscopy: Cyst contents does not show a broad lipid spectrum as they are filled with water fluid.
