Ossified rathke's cleft cyst: A rare variant

摘要

Rathke's cleft cysts (RCC) are predominantly sellar-suprasellar lesions thought to arise from remnants of embryologic Rathke's pouch during fourth week of development. The presence or the absence of calcification is an important feature in distinguishing them from other commonly encountered cystic lesions in the sellar-suprasellar region.[1] Craniopharyngiomas very commonly show calcifications and the presence of the same is uncommon in Rathke's cleft cyst. The case presented here is one of such uncommon variants.
