There is a well-defined mass centered in the sellar and suprasellar region, not compressing the optic chiasm, no extension into the adjacent cavernous sinuses. It elicits a hyperintense signal on T2/FLAIR, an isointense signal on T1, no restricted diffusion on DWI, and no enhancement in the post-contrast study apart from the peripheral thin enhancing rim.
The mass is seen in midline location, no identified septations, fluid-fluid levels, and hypointense rim on T2.
MRI findings represent predominantly cystic pituitary region mass, likely cystic pituitary adenoma or Rathke cleft cyst.
The midline location and absence of septations, fluid-fluid levels, and hypointense rim on T2 favor the Rathke cleft cyst rather than the cystic pituitary adenoma 1.
