The Angiographic Delineation of Sellar and Parasellar Masses

The anatomic and normal angiographic appearance of small vessels which vascularize the neural and glandular structures in and about the sella turcica is discussed. Findings in a group of abnormal cases illustrate alterations in the local vessels which occur in the presence of sellar and parasellar masses. Some of the changes seen appear to be helpful in differentiating the various types of tumor. Tumors in which characteristic dislocations were seen include pituitary adenoma, “empty” sella, nonmeningiomatous parasellar masses, parasellar meningioma, craniopharyngioma, optic chiasm glioma, and colloid cyst of the third ventricle.
