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: may demonstrate displacement of the A1 segment of theanterior cerebral artery (ACA) MR spectroscopy: cyst contents may show a broad lipid spectrum, with an otherwise flat baseline 6 (Images courtesy of RadsWiki)
