The multifocal glioblastomas (GBM) are tumors with multiple discrete areas of contrast enhancing tumors which have considerably poorer prognosis than solitary GBM. Median overall survival of diagnosed pa-tients almost twice as less than solitary presentation. We present a case report of multifocal GBM. A 72-year old right-handed male was evaluated at the Neuro-Oncol-ogy Clinic of Baylor Scott and White Hospital (Central Division). Patient presented at this hospital because of persistent progressive headaches, confusion, and an in-cident of fall. Physical evaluation revealed neurological impairments. Brain magnetic resonance imaging (MRI) revealed heterogeneous contrast enhancing lesions with associated vasogenic oedema. Patient underwent a stereo-tactic biopsy analysis of the larger lesion and pathology evaluation concluded an isocitrate dehydrogenase 1 and 2 wild type GBM with unmethylated O-6-methylgua-nine-DNA methyltransferase. Treatment remedies: Pa-tient received 4 weeks concurrent radiation therapy along with combination of temozolomide at dose of 75 mg/m2 followed adjuvant temozolomide for 10 cycles with bev-acizumab at 10 mg/kg every 2 weeks and Optune treat-ment. Post treatment evaluation: Repeat MRIs showed near complete resolution of the tumors at 26 months of treatment along with improvement of neurological status. Conclusion: Due to limitations of surgical manipulations in multifocal GBM diagnosed patients, combinational chemo and radiation therapy is the treatment of choice for most cases. Using additional novel treatment with non-in-vasive therapeutic device proven to be effective is another excellent approach to the established practice. Therefore, combination therapy of Optune plus temozolomide and bevacizumab might be a promising remedy for newly di-agnosed multifocal glioblastomas.
