Cystic retrochiasmatic craniopharyngiomas may reach enormous size by expanding into the posterior fossa along the retroclival area, which is very unusual finding. A 5-year-old boy presented with headache for 2 month. On the neurological examination, it was normal. Initial magnetic resonance (MR) images revealed a huge, thin-capsuled multi-cystic mass, which extended around brain stem & extending bilaterally along the base of the middle and posterior cranial fossa. Subtotal excision of the cystic wall was done followed by applying of a catheter within the cyst attached to a reservoir with a favorable outcome.

Craniopharyngiomas usually emerge in the infundibulo-hypophyseal axis of the sella and suprasellar region occupies the suprasellar cisterns, however may extend in any direction. The horizontal extension of the tumor may be anteriorly into the pre-chiasmatic cistern and sub-frontal space, may extend laterally into the sub-temporal space, or may extend posteriorly into the prepontine and interpeduncular cisterns, cerebellopontine angle and then to the foramen magnum. 7 However, rarely extensive tumors may extend anteriorly in the pre-chiasmatic cistern and posteriorly into the 3rd ventricle and down along the clivus. Approximately 4 % of the cases have posterior fossa extension. 2,6
