Glioblastoma imitating a cavernoma radiologically: A unique image report

Abstract

Background: Glioblastoma is the most common primary malignant brain tumor with characteristic radiological features in most cases. Case Description: We highlight an unusual case of a 54-year-old woman, neurologically intact, with a diagnostically challenging lesion. The patient’s magnetic resonance imaging revealed a left frontal lesion with surrounding edema and a hemosiderin ring, misleading it to be a cavernoma. Intraoperatively, the lesion was found to be a solid tumor with hematoma and was confirmed to be glioblastoma on histopathology. Conclusion: The dilemma associated with our patient’s radiological findings and longstanding history of epilepsy is rare and a diagnostic challenge.
