Gross total excision of pediatric giant cystic craniopharyngioma with huge retroclival extension to the level of foramen magnum by anterior trans petrous approach: report of two cases and review of literature

摘要

Purpose Craniopharyngiomas with a large posterior fossa extension beyond the level of the foramen magnum are very rare and usually removed in two stages. The objective of this paper is to report that such rare cases of giant cystic predominantly retrochiasmatic retroclival craniopharyngiomas can be completely excised by an anterior transpetrous approach in a single stage.
