  • Title: CT and MRI of sellar spine with upward extension of the pituitary gland: case report.
    Author: Matsumoto K, Uchino A, Kato A, Kudo S, Kuno T.
    Journal: Eur Radiol; 1997; 7(2):287-8. PubMed ID: 9038132.
    Abstract:
    This is a report of CT and MRI findings in a patient with a sellar spine which caused deformity of the pituitary gland. The sellar spine is an infrequent anatomical variant characterized by an osseous spine which arises in the midline from the anterior aspect of the dorsum sellae and extends into the pituitary fossa. The CT and MRI findings of sellar spine have been described in previous reports; however, only one investigator reported deformity of the pituitary gland as revealed by CT. This is the first report of the MRI finding of the sellar spine associated with a deformity and superior extension of the pituitary gland, mimicking pituitary hypertrophy.
