[The clinical features and perioperational managements of craniopharyngiomas in posterior fossa]

To investigate the clinical features and perioperational managements of craniophayngiomas located in posterior fossa.Nine patients with craniopharyngioma situated in posterior fossa were included in the study. The clinical manifestations, neuroimage features, operational treatment, and perioperational managments were retrospectively analyzed. RESULTS; All tumors associated with big or huge volume, arised from sellar/suprasellar region and extended into posterior fossa. Tumors showed cystic lesions in 2 cases and cystic-solid lesions in 7 cases. Headache was the most common symptoms (6/9), followed by cranial nerve deficit (4/9) and endocrine dysfunction(3/9). The supra- and infra-tentorial approaches were the optimal approaches for removal these tumors (7/9). Cranial nerves deficit was the most common complication in perioperative period. No perioperational death occured, most of the patients showed good recovery during the fellow-up period.Craniophayngiomas in posterior fossa shows different clinical manifestations, radiological features, surgical complications to the tumor in sellar/suprasellar region.
