title: [Glioblastoma of the cerebellum: report of an autopsy case associated with intratumoral hemorrhage and CSF seedings].
abstract: An autopsy case of glioblastoma of the cerebellum associated with an intracerebellar hemorrhage and showing CSF seedings is reported. A 26 year-old male was admitted to our hospital with a 10-day history of headache, nausea and vertigo. On admission, disturbance of consciousness (10-20 by JCS), irregular respiration and central fixation of both eyes suggesting increased intracranial pressure and early stage of central herniation were recognized clinically. The cerebellar signs of dysmetria and nystagmus were also observed. CT scan and angiography revealed an avascular large mass in the right cerebellar hemisphere, obstructive hydrocephalus and upward transtentorial herniation. On MRI study, the mass was demonstrated to be a subacute hematoma with a small tumor in its margin. Total removal of the tumor and aspiration of the hematoma were performed. Histological examination revealed a highly cellular and pleomorphic astrocytic tumor with scattered small necrosis and glomeruloid capillary endothelial proliferation, typical of glioblastoma multiforme. During postoperative radiochemotherapy (focal irradiation to the posterior fossa), the tumor showed rapid regrowth and a second look operation was performed. He was readmitted 3 weeks after radiochemotherapy with complaints of severe headache, nausea and lumbago. He then suddenly became dyspnea, tetraplegic and bradycardic. Neuroradiological investigation revealed multiple masses in the suprasellar region, medulla oblongata and the cervical spinal cord, but no recurrence in the cerebellum. Malignant cells were noted on CSF cytology. During chemotherapy for CSF tumor dissemination, his condition deteriorated rapidly and he died 7 months after the onset of symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)
