Abstract

BACKGROUND: Glioblastoma can mimic various pathologies, including arteriovenous malformation, hemorrhage from ischemic stroke, cerebral contusion, metastatic disease, lymphoma, and infection. The literature is limited regarding diagnostic confusion with meningioma. Herein, we present 2 patients that exhibited imaging, including cerebral angiography during preoperative embolization, which was consistent with meningioma, but where final surgical diagnosis revealed glioblastoma.

CASE DESCRIPTION: Case 1 was a 57-year-old woman presenting with headache, ataxia, and memory lapses for the past month. Brain magnetic resonance imaging (MRI) demonstrated a heterogeneous-enhancing right temporoparietal mass with broad contact along the right tentorium, cerebrospinal fluid (CSF) cleft sign, and dural tail sign-consistent with meningioma. Patient underwent angiography with successful polyvinyl alcohol foam (PVA) particle embolization of the petrosquamosal branch of the right middle meningeal artery (MMA) and meningeal branch of the right occipital artery, resulting in significant devascularization of the tumor blush. Subsequently, the patient underwent tumor resection, where pathology revealed glioblastoma. Case 2 was a 60-year-old man presenting with right hemiparesis. Brain MRI demonstrated a left parasagittal, heterogeneous-enhancing mass abutting the falx with a dural tail sign-consistent with meningioma. Patient underwent angiography with successful PVA particle embolization of the left MMA, resulting in significant devascularization of the tumor blush. Patient underwent a tumor resection where pathology revealed glioblastoma.

CONCLUSIONS: 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.
