A. To understand the anatomy of sellar and parasellar region. B. To illustrate the spectrum of tumours and other lesions affecting the sellar and parasellar region. C. To demonstrate the salient features differentiating these lesions. D. To frame a diagnostic algorithm for approaching sellar and parasellar lesions.

Sellar, parasellar and suprasellar masses are very common in neuroradiological practice. MRI with contrast enhancement is the gold standard in imaging of sellar and parasellar region. In this pictorial review, a brief description of anatomy of sellar and parasellar region is provided, with reference to the important landmarks. The comprehensive pictorial review encompasses lesions such as pituitary adenoma, meningiomas, craniopharyngiomas, Rathkes cleft cyst, aneurysm, carotid cavernous fistula, metastasis, chiasmatic and hypothalamic gliomas, hamartoma,germinoma,empty sella syndrome, chordoma, chondrosarcoma, dermoid /epidermoid cyst,arachnoid cyst, sarcoidosis, histiocytosis, lymphoma , schwannoma, tuberculosis and other infections.Characteristic imaging features of these lesions such as location, internal architecture, displacement/invasion or adjacent structures and contrast enhancement are discussed. A flow chart is provided for differentiation, which has an impact on management
