Spinal Cord Glioblastoma Multiforme with Intracranial Dissemination: Case Report

A case of spinal cord glioblastoma multiforme with intracranial dissemination is reported. A 23-year-old female was admitted to a local hospital complaining of lumbago. Myelography revealed an intramedullary thoracic tumor. The tumor was partially removed through a laminectomy at Th 11-L1. The histological diagnosis was glioblastoma multiforme, and focal irradiation (total 50 Gy) was given. Eight months after the operation, symptoms of increased intracranial pressure appeared. Computed tomographic (CT) scans showed marked hydrocephalus, and multiple tumors at anterior horns of bilateral lateral ventricles. A ventriculoperitoneal shunt and an Ommaya reservoir into the left lateral ventricle were emplaced. Three months later, she was transferred to our hospital. CT scans showed enhanced lesions in the fourth ventricle, anterior horn of the left lateral ventricle, septum pellucidum, and pituitary gland. Suboccipital craniectomy was performed, and the mass around the fourth ventricle was partially removed. Histological examination of the tumor specimens showed glioblastoma multiforme. Postoperatively, she received whole brain irradiation (total 50 Gy), and intrathecal injection of β-interferon via the Ommaya reservoir. However, she died of respiratory insufficiency. It is considered that the spinal cord glioblastoma multiforme disseminated into the intracranial space.
