A Rare Case of Glioblastoma Multiforme with Osseous Metastases

Glioblastoma multiforme is the most common malignant primary central nervous system neoplasm in adults. It has a veryaggressive natural history with a median overall survival estimated at 14.6 months despite multimodality treatment. Extracranialmetastases are very rare with few case reports published to date. We report the case of a 65-year-old male who underwent maximalsafe resection for a newly diagnosed brain mass after presentation with new neurologic symptoms. He then received standardpostsurgical adjuvant treatment for glioblastoma. Subsequently, he underwent another resection for early progressive disease.Several months later, he was hospitalized for new-onset musculoskeletal complaints. Additional investigation revealed newmetastatic osseous lesions which were initially felt to be a new malignancy. )e patient opted for supportive care and died 12 dayslater. Despite choosing no treatment, he elected to undergo a bone biopsy to understand the new underlying process. Results werethat of metastatic GBM and were reported after the patient expired. Physicians caring for patients with GBM and new non-neurologic symptoms may contemplate body imaging.
