Sellar lesions mainly constitute pituitary adenomas, craniopharyngiomas and benign cysts. Rathke's pouch cyst is a developmental sellar and/or suprasellar cystic lesion lined by a single layer of ciliated cuboidal or columnar epithelium, which rarely be comes symptomatic. The authors present an interesting case of intrasellar Rathke's pouch cyst, with a presenting feature of acute pituitary apoplexy. This was a 19 year old healthy male who had developed sudden headache and visual disturbance. Neuro-radiological imaging revealed a mass in the sella. Via transsphenoidal approach a haemorrhagic intrasellar cystic lesion was removed and was confirmed as a haemorrhagic Rathke's cleft cyst by histopathological examination. Interesting clinical presentations and the neuroimaging findings are described and discussed.
