Rapid progression of pituitary hyperplasia in humans with primary hypothyroidism: Demonstration with MR imaging. Small T2 hypointense intracystic nodules may also be present.It usually has solid components and septation and does not follow the CSF signal intensity on MR images.Although the signal intensity is very similar to an empty sella, mass effect on the infundibulum will be seen.In addition, the margins of the cyst may be visible on high-resolution MR images.This tumor is more commonly located in the CP (cerebellopontine) angle, but it can exist in the suprasellar region and can appear very similar to a cyst on T1- and T2-weighted sequences.It frequently engulfs the adjacent vasculature rather than displacing vessels.Most importantly, epidermoid cysts are bright on diffusion-weighted images with corresponding dark signal on ADC (apparent diffusion coefficient) due to the presence of keratin.Incomplete suppression (“dirty CSF”) is seen on FLAIR images.This suprasellar tumor most commonly presents as a multi-loculated cystic and solid mass that frequently calcifies and does not follow the CSF signal intensity.
