Absent septum pellucidum with associated mild flattening of the anterior horns of the lateral ventricles with point-down appearance of the inferior aspect of the anterior horn: (best appreciated on coronal T2-weighted images).
Ectopic posterior pituitary gland: (best appreciated on sagittal T1-weighted images as a high signal focus seen at the median eminence).
