  • Title: Sellar emptiness on routine magnetic resonance imaging.
    Author: Hardjasudarma M, White KE, Nandy I, Burns PL.
    Journal: South Med J; 1994 Mar; 87(3):340-3. PubMed ID: 8134855.
    Abstract:
    Magnetic resonance imaging (MRI) has provided a clear view of the sella turcica and the pituitary gland, even on "routine" procedures that invariably include the sagittal T1-weighted sequence. A pituitary gland that does not fully occupy the sella is a common observation, even in normal individuals. Terms such as "empty sella" and "partially empty sella" have become more commonly used, occasionally giving rise to some confusion regarding their clinical significance. In a prospective study of 50 "near-normal" patients, based exclusively on the midsagittal T1-weighted image, we have found a statistically significant increase in sellar emptiness with age, a phenomenon that is more prominent in women. The finding of an empty or partially empty sella on routine MRI of the brain is therefore usually of no clinical significance.
