Fig. 2.

Magnetic resonance imaging of the brain/pituitary with and without gadolinium. Coronal view (from top left in the clockwise direction: coronal FIESTA image, coronal T1-weighted image, coronal susceptibility weighted image, coronal 3-dimensional view T1-weighted image) showing rim enhancement and blooming effect (hypointensity that becomes more pronounced on susceptibility-weighted imaging). Constriction at the diaphragma sellae, resulting in a dumbbell-shaped mass, can also be appreciated.
