Author Name : Waad Rasheed Alsubaie, Amnah almutrafi, Fahad Alsufiani
Introduction: The Glioblastoma is a malignant brain tumor with a poor prognosis. The metastasis rarely occurs due to the lack of lymph and blood access to the tumor cells. Sites of glioblastoma metastasis are the liver, lungs, and parotid gland. Seizures are the early signs of glioblastoma, and its survival rate is low.
Case Report: We present a case of 38-years old female with World Health Organization Grade IV IDH-mutant Glioblastoma that evolved from Grade II Astrocytoma. The patient underwent three resection surgeries of the tumor and was treated with chemotherapy and Temozolomide. After the third surgery, glioblastoma metastasized to the right parotid gland.
Conclusion: In our case, the progression of Grade II astrocytoma to Grade IV glioblastoma is highlighted. It is associated with seizures and shows ipsilateral metastasis to the parotid gland.
