FIG 2. Images from case 2.

A, Unenhanced midline sagittal spin-echo T1-weighted image (625/13/4) shows a small hyperintensity at the median eminence typical of ectopic posterior pituitary lobe, with a second small hyperintensity extending downward into the upper infundibulum (arrows). The infundibulum is thinned, with a small pituitary gland and sella turcica. The splenium of the corpus callosum is small.

B, Axial fast spin-echo T2-weighted images (5200/102/3) show small heterotopic nodules isointense to gray matter, above the frontal horns (arrowheads).
