  		Fig 1. Coronal T1-weighted (A), T2-weighted (C), and postcontrast T1-weighted (B) MR images showing an intrasphenoidal cyst hypointense on T1-weighted images and hyperintense on T2-weighted images, causing destruction of the sella turcica and compression of the pituitary gland and optic chiasm. After gadolinium-diethylene-triaminepentaacetic acid administration, there is a slight enhancement of the outer border of the lesion.
