This is a retrospective study that included 54 patients with a cystic pituitary adenoma and 28 patients with a Rathke cleft cyst who underwent MR imaging followed by surgery. Regression analysis showed that cystic pituitary adenomas and Rathke cleft cysts could be distinguished on the basis of the presence of a fluid-fluid level, septation, an off-midline location, and the presence of an intracystic nodule.

The authors evaluated the effect of jugular compression on brain tissue stiffness and CSF flow by evaluating 9 volunteers, with and without jugular compression, with MR elastography and phase-contrast CSF flow imaging. The shear moduli of the brain tissue increased with the percentage of blood draining through the internal jugular veins during venous compression. Subjects who maintain venous drainage through the internal jugular veins during jugular compression have stiffer brains than those who divert venous blood through alternative pathways.
