(a, b) Pre- and postcontrast brain MRI images of case 1 show that posterior pituitary bright spot is not visualized. (c, d) Pre- and postcontrast brain MRI images of case 1 at four months postpartum show return of posterior pituitary bright spot.

Brain MRI (Figures 1(a) and 1(b)) showed loss of the normal hyperintense posterior pituitary signal consistent with AVP depletion. Four months postpartum, repeat MRI (Figures 1(c) and 1(d)) showed return of the hyperintense posterior pituitary signal, consistent with AVP repletion.

(a, b) Pre- and postcontrast brain MRI images of case 2 show that posterior pituitary bright spot is not visualized and that the anterior pituitary appears small for age and postpartum state.
