Abstract
Ke yW ords. sellar mass, parasellar mass, pituitary adenoma, cystic sellar lesions, sellar neoplasms Several types of lesions may present within the sella turcica and in parasellar areas, of which the most common are pituitary adenomas. Less commonly, sellar lesions are of non-pituitary origin with a broad range of potential etiologies including neoplastic, non-neoplastic cystic lesions, inflammatory and infectious lesions, vascular lesions and pituitary hyperplasia [1]. Differentiating among these various causes may be difficult, as they share similar clinical and radiographic features and easily mimic each other and pituitary adenomas. Making the correct preoperative diagnosis is of clinical relevance since the treatment of choice for many of these non-pituitary sellar masses differs from that of a pituitary adenoma. An overview of the clinical and radiographic features of the more common lesions as well as their management is provided in this article.
