Magnetic Resonance Imaging Reveals a Pronounced Treatment Response of a Isocitrate Dehydrogenase- and B-Raf Proto-Oncogene-Wildtype Epithelioid Glioblastoma.

Abstract:

:We here report findings on magnetic resonance imaging from a 60-year-old patient with an epithelioid glioblastoma of the corpus callosum treated with radiotherapy in combination with concomitant and adjuvant temozolomide. Neuropathology revealed a highly aggressive molecular subtype of the epithelioid glioblastoma without an isocitrate dehydrogenase and B-Raf proto-oncogene mutation or a O6-methylguanine-DNA-methyltransferase promoter hypermethylation. This subtype is typically associated with an unfavorable clinical course and poor overall survival. Unexpectedly, the first follow-up magnetic resonance imaging 10 weeks after chemoradiation completion revealed an early and almost complete treatment response.

  • A Single-Institution Retrospective Study of Jugular Foramen Schwannoma Management: Radical Resection Versus Subtotal Intracranial Resection Through a Retrosigmoid Suboccipital Approach Followed by Radiosurgery.

    abstract:BACKGROUND:Despite advances in skull base surgery, achieving effective surgical management of jugular foramen schwannomas (JFSs) that avoids postoperative cranial nerve (CN) deficits remains a challenge. Subtotal resection followed by radiosurgery (rather than radical resection) is increasingly being viewed as a better...
