MRI of the pituitary gland. Sequences FSET1 and FSET1 after enhacement, coronal images. The pituitary stalk is difficult to trace, in unenhanced and enhanced images too. The enlargment of the hiperintensive structure, corresponding the ectopic posterior pituitary lobe, in FSTE1 after enhacement suggests the presence of the vascular structures of the pituitary stalk in adherence to the ectopic lobe, what indirectly confirms the lack of continuity of the further section of pituiatry stalk.
