FIG 1. Images from case 1, with typical findings of ectopic posterior pituitary lobe.

A, Unenhanced midline sagittal spin-echo T1-weighted image (625/13/4) shows hyperintensity corresponding to ectopic posterior pituitary lobe at the median eminence (short arrow). The pituitary gland and sella turcica are small, with a thin infundibulum (long arrow).

B, Coronal T1-weighted spoiled gradient-recalled image shows a small heterotopic nodule, isointense to gray matter, above the left trigone (arrow).
