A Case of Glioblastoma, Isocitrate Dehydrogenase Wild Type, With Widely Disseminated Osseous Metastasis

Abstract

Glioblastoma, isocitrate dehydrogenase (IDH) wild type, is an aggressive primary brain malignancy with a poor prognosis, despite treatment including surgery, chemotherapy, and radiation therapy. Few patients with glioblastoma develop metastasis outside the neuroaxis, likely due to disease progression in the brain prior to extraneural dissemination. The driving mutations of tumors in patients with extraneural metastases are not well described. In this case, we present a severe case of extraneural metastatic glioblastoma, as well as the genetic mutations of the tumor.
