Preschooler with growth hormone deficiency

MRI of ectopic posterior pituitary gland
Sagittal T1 MRI without (above) and with contrast (below) of the sella shows the high signal intensity posterior pituitary bright spot, which should be located posteriorly in the sella turcica, is instead located in the superior aspect of the pituitary stalk / inferior aspect of the hypothalamus. The pituitary gland is otherwise unremarkable.

The diagnosis was ectopic posterior pituitary.
