Abstract
BACKGROUND: Glioblastoma multiforme (GBM) is one of the most aggressive malignant brain tumors. Intracranial GBM metastases to the spine are rarely detected clinically. Secondary gliosarcomas after treatment of primary GBM are rarely described.
CASE PRESENTATION: Herein, we report the case of a 53-year-old woman who presented to our emergency room with progressive headache and weakness on the left side. Plain computed tomography and contrast magnetic resonance imaging of the brain revealed an approximately 6.8 cm × 4.5 cm right temporoparietooccipital intraaxial cystic tumor with surrounding diffuse perifocal edema that caused midline shift toward the left. Emergency craniotomy was performed to remove the tumor, and pathological examination revealed GBM. The patient received proton beam therapy, Gliadel implantation, and oral temozolomide chemotherapy as well as targeted therapy with bevacizumab. Approximately 15 months after diagnosis, she underwent surgical resection of the right temporal recurrent tumor and was newly diagnosed as having a metastatic spinal tumor. Pathologically, the right temporal and metastatic spinal tumors were gliosarcoma and GBM, respectively.
CONCLUSIONS: Concurrent spinal metastasis and gliosarcomatous transformation, which are two types of GBM complications, are rare. To our knowledge, this is the first report of a case of recurrent GBM with gliosarcoma after proton bean therapy.
