Sellar region: magnetic resonance imaging assessment of uncommon tumors and pseudotumors

Abstract

Objective: To show the usefulness of magnetic resonance imaging in the anatomic and pathologic characterization of the sellar region, emphasizing the differential diagnosis of uncommon non-adenomatous tumors and pseudotumors studied in our institution.

Conclusion: The sellar region is a complex anatomic space with diverse types of tissues from which a wide spectrum of diseases can arise. Magnetic resonance imaging's high tissue resolution and ability to characterize the patterns of tumor growth and biological behavior make it the best imaging technique to study this region.
