Skeletal Metastases in a Treated Case of WHO Grade IV Glioma without Relapse of Primary Tumor: A Rare Entity

Glioblastoma is the most common primary malignant brain tumors of the adult with a very dismal prognosis, representing 12-15% of all intracranial tumors in adult. The mean age of survival after diagnosis is approximately 14.6 months despite treatment. However, extracranial metastases are rare in the case of glioblastoma. We report a case of a 37-year-old female who had right frontal lobe glioblastoma and was operated on in December 2019 and received radiotherapy. There was complete remission of the tumor. After 1 year, she developed a low backache and pain in her right hip. Investigations revealed new-onset lesions in the bones. HPE proved the lesions to be metastatic glioblastoma.
