Case Report Collision tumor of meningioma and craniopharyngioma: a case report
نویسندگان
چکیده
Meningiomas are the commonest benign intracranial tumor, accounting for 13-26% of all primary intracranial tumors. They can arise from the dura at any site. Craniopharyngiomas are uncommon epithelial tumors which represent only 2-5% of all primary intracranial neoplasms and arise anywhere along the path of the craniopharyngeal duct. The co-existence of meningioma and craniopharyngioma has rarely been reported. Herein, we report an unusual case of an anterior fossa meningioma occurring together with a craniopharynyioma, which were radiologically not distinguishable in preoperative imaging. The clinical presentation, preoperative imaging, surgical treatment, histologic features of the two tumors and possible proposed mechanisms leading to the development of two different tumor types in one patient are discussed.
