Magnetic resonance imaging of the brain (July 2016). Plane T1-weighted images (a: coronal plain, b: sagittal plain) showing a 2.5-cm pituitary tumor (arrows) and deformed hypophyseal stalk, with no compression on the optic chiasm. The physiological high-intensity signal (*) was found in the posterior pituitary gland (c: sagittal plain). T2-weighted images (d: coronal plain, e: sagittal plain, f: transverse plain) revealed a mixed pattern of solid and liquid components in the pituitary tumor, with fluid-fluid levels (short arrows)
