E2465. The Sella Turcica, Home to More Than Just the Pituitary Gland: An Anatomic Approach to Intrasellar and Parasellar Masses
Rochester General Health
Sella and parasellar-based masses have long been difficult to accurately diagnose due to the narrow confines of this space. The purpose of this study is to demonstrate to the radiologist-in-training and in practice the utility of anatomic landmarks and morphology in identifying the epicenter of a sella or parasellar lesion. After the identification of the epicenter, this presentation will help guide the radiologist in narrowing the differential of a lesion based on its composition as well as its MRI characteristics.
Educational Goals / Teaching Points
The teaching points are to first understand the anatomy and the relationships on the sella and parasellar space. Next, using these anatomic landmarks and morphology, identifying the epicenter of a sella or parasellar lesion. Finally, narrow the differential as accurately as possible based on the epicenter of the lesion, composition, and MRI signal characteristics.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
MRI imaging modality with multiple planes and sequences will be used to understand the anatomy and pathophysiology of various sella and parasellar lesions.
Using MRI imaging and contrast enhancement, it is feasible to narrow the differential of sella and parasellar lesions based on its epicenter, composition, and morphology.
