Brain magnetic resonance imaging scans. a Diffusion-weighted imaging (DWI). b T2-weighted (T2w) imaging. c, d T1-weighted (T1w) imaging + gadolinium. Images show a multilocular intra and suprasellar pituitary cystic mass exhibiting a typical rim enhancement pattern, with the central part being in high-intensity DWI/T2w and low-intensity T1w. This pituitary abscess is associated with peripheral edema (b) and is responsible for local compression mainly on the optical chiasma
