Overview
MRI
Adamantinomatous
The findings on the 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.
