Craniopharyngioma of the Pineal Region

Craniopharyngiomas generally develop either in the suprasellar region or in both suprasellar and intrasellar regions. We report on a nontypical location of the craniopharyngioma in the pineal region. An 8-year-old boy was admitted to the department of pediatric neurosurgery in a grave condition. An MRI scan of the brain was performed after the neurological examination and revealed a large neoplasm situated in the posterior part of the III ventricle and in the pineal region, measuring 8.5x6.5x5 cm. The size of the tumor and its location meant it was occluding three ventricles, with subsequent hydrocephaly. Total removal of the tumor was carried out. Microscopic investigation of the tissue removed showed the typical structure characteristic for craniopharyngioma of the adamantinomatous type. Results of a consultation 6 months after the operation revealed that the patient was feeling well, attending school regularly and had finished the first semester with excellent results. On control MRI scan no tumor was found.
