Anomalien der Sella

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Persistent craniopharyngeal canal. Axial (a) and sagittal (b) CT shows a markedly enlarged persistent craniopharyngeal canal. Coronal fat-suppressed T1WI shows inferior extension of enhancing pituitary tissue within the abnormally enlarged craniopharyngeal canal (c)

Magnetic

resonance imaging of sellar and juxtasellar abnormalities in the paediatric population: an imaging review. Pituitary duplication. Coronal post-contrast images (a and b) show two pituitary stalks which extend inferiorly into separate duplicated pituitary glands. Sagittal T1WI (c) shows marked thickening of the hypothalamus, referred to as a pseudohamartoma, which has intermediate signal. The pseudohamartoma showed no contrast enhancement (not shown)
