The most common sellar pathology that merits neurosurgical attention is the pituitary adenoma. However, some developmental, inflammatory, and neoplastic lesions may primarily or secondarily involve the sella, mimicking pituitary tumors. Advances in imaging and endocrinological assessment have helped in the recognition of these less common sellar, supra sellar pathologies, which may occasionally create confusion in management. The most common developmental anomaly is the Rathke's cleft cyst and an increasingly recognized inflammatory pathology is the spectrum of hypophysitis. Neoplasms, viz. Craniopharyngioma, Germinoma, Langerhans's cell histiocytosis or metastasis, have more distinctive features in various age groups and are more likely to be correctly diagnosed on current imaging and managed accordingly. This review looks at mainly intraparenchymal pathologies, namely Rathke's Cleft Cyst and various hypophysitides, and will discuss their management strategies.
