Glioblastoma Mimicking Meningioma: Report of 2 Cases

Abstract

Glioblastoma can mimic meningioma on MRI with dural tail sign, CSF cleft sign, and broad dural contact. Moreover, cerebral angiography can reveal tumor feeders commonly associated with meningioma. These features can contribute to diagnostic confusion. Based on these 2 cases, preoperative embolization of tumor feeders is possible with glioblastoma.
