(a) The left hand and wrist bones of the first patient which is consistent with a bone age of 3 years. (b) Posterior-anterior image of the left knee of the second patient reveals the open epiphysis of the growth plate.

Plain film X-ray of the knee showed open epiphyseal plates (Figure 1).
(a) The first patient's sagittal MR image without contrast for the pituitary; the solid arrowhead points to the posterior pituitary lobe (bright spot), while the dashed arrowhead points to the supposed pituitary stalk which is absent. (b) Coronal image without contrast for the first case shows the ectopic bright spot close to the optic chiasm. (c) Noncontrast sagittal view for the pituitary in the second case where the solid arrow points to the ectopic bright spot and the dashed arrowhead points to the absence of pituitary stalk. (d) Contrast coronal image for the second case.
