Pituitary magnetic resonance imaging study. (A) Gadolinium-enhanced coronal T1-weighted image (March 2014). Slightly enlarged pituitary gland (12.8 mm; solid arrow) and thickened stalk (3.9 mm; dotted arrow). (B) Sagittal T1-weighted image (March 2014). Loss of the normal hyperintense signal of the posterior pituitary (solid arrow). (C) Gadolinium-enhanced coronal T1-weighted image (March 2015). Normalization of pituitary size (solid arrow) and stalk width (dotted arrow). (D) Sagittal T1-weighted image (March 2015). Persistent loss of the normal posterior lobe T1 hyperintensity (solid arrow).
