[Osteo-medullary metastases from cerebral glioblastoma]

A 55 year old female with a history of three different malignancies including a cerebral glioblastoma developed two bone metastases (in the spine and iliac crest). Histologic and immunohistochemical studies of biopsy specimens demonstrated the presence of glial fibrillary acidic protein, establishing that the bone tumors were metastases from the glioblastoma. Specific features of these rare metastases are discussed.
