To review MRI most typical and remarkable imaging findings in sellar masses. 2.
To remember the importance of complete anatomical delimitation and correct description of invasive sellar masses. 3.
To identify most common pitfalls and to be able to remember most important differential diagnosis.
We performed a retrospective analysis of patients with remarkable findings in sellar region in our institution with MR 1,5T and 3 T between the years 2016 and 2018,
correlating imaging characteristics and histopathological findings.
Findings and procedure details
• Anatomy of the sellar and parasellar region. • MRI sellar protocol. • WHO classification of pituitary tumors. • MRI features: Tumor shape,
characteristics and enhancement patterns. • Knosp’s and Hardys radiological classification. • MRI evidence of macroscopic invasion of surrounding tissues and structures. Introduction: The sellar region is a central nervous system complex anatomical area composed by relevant anatomical structures.
The region is surrounded by suprasellar and...
Masses of the sella turcica can exhibit an aggressive behavior,
characterized by invasion of surrounding tissues and anatomical structures.
That may leads to resistance to conventional treatment and in consequence frequent recurrences. A correct interpretation of the most typical imaging findings is important to accurately diagnose and classify pituitary tumors according to their prognostic potential.
