ABSTRACT
Purpose To analyze the clinical and pathological features of intracranial tumor in children. Methods 221 cases of in-tracranial tumors in children ( ages≤18 years) were retrospectively analyzed. Results The cases of intracranial tumor in children ac-counted for 7. 21% of total cases in our hospital during the same period. There is no documented gender bias. There were only 14 cases (6. 33%) with age less than 3 years old. The supratentorial tumors were 153 cases (69. 23%) and infratentorial tumors were 68 cases (30. 77%) . The most frequently affected sites were the cerebral hemispherse, sellar region, vermis and the fourth ventricle. There were 89 benign tumor and 132 malignant tumor in this series of cases. The most common five tumors were astrocytic tumors (30. 32%), embryonal tumors (19. 00%), craniopharyngiomas (11. 76%), ependymal tumors (8. 14%) and germ cell tumors (5. 88%). Conclusion The morbidity of intracranial tumors in children has increased in the recent years. The histological classifica-tion of intracranial tumors in children is multiple and it is essential to make a correct diagnosis.
ABSTRACT
Objective To explore the methods for diagnosis and treatment of malignant meningioma.Methods The clinical data of twenty-nine patients with malignant meningioma were retrospectively analyzed.Results Among the 29 patients,15 underwent Simpson Ⅰ resection,8 underwent Simpson Ⅱ resection and 6 had Simpson Ⅲ resection.Among these patients,Twenty-five cases were successfully followed up for 20-100 months.There are 11 cases who occurred relapse (44％),of whom 2 received Simpson Ⅰ resection,3 received Simpson Ⅱ resection and all the 6 cases receiving Simpson Ⅲ cases.Conclusion Head CT and MRI examination is helpful to diagnose malignant meningioma.The treatment mainly involved surgical resection combined with radiation and chemotherapy,with high postoperative recurrence rate and short survival time depending on the differentiation of the tumor.
ABSTRACT
Plasma cell myelomas generally manifest as bone or soft-tissue tumors with variable mass effects, pain, and infiltrative behavior. Extramedullary involvement occurs most commonly in the spleen, liver, lymph nodes, and kidneys, but intracranial involvement in plasma cell myeloma is a rare extramedullary manifestation. These authors recently encountered a case of intracranial involvement of plasma cell myeloma. A 69-year-old man was hospitalized for headache and mental changes. Brain CT showed subdural hemorrhage caused by plasma cell myeloma. Plasma cell myeloma with intracranial involvement has poor prognosis, and the patient in this case died from acute complications, such as subdural hemorrhage. Based on this case report, it is suggested that more effective treatment regimens of plasma cell myeloma with intracranial involvement be developed. Moreover, a screening method and decision on the appropriate time for intracranial involvement are needed for plasma cell myeloma patients.

The majority of deaths due to intracranial tumors are preceded by long periods of symptoms, resulting in diagnosis of the tumors. And introduction of CT and MRI have led to increased early detection of intracranial tumors. Nonetheless, sudden unexpected deaths from intracranial tumors are rarely encountered at autopsy. We report an autopsy case of 2-year-old boy who died from medulloblastoma.

Primary lymphoma is rare lesion of the intracranial neplasm. We have recently experienced a case of primary lymphoma invoving cerebellar vermis and hemisphere. The patient presented with headache, vomiting, ataxia and dysmetria. The brain CT scan and MR imaging revealed round mass lesion involving the left cerebellar hemisphere and vermis with minimal surrounding brain edema. On vertebral angiography, tumor stain appeared during the late arterial phase. Preoperative CSF analysis showed no specific abnormal findings. The CSF cytology was normal. The mass was surgically removed and the histological feature was diffuse histiocytic lymphoma. In the postperative and postradiation period, the metastasis occurred to the head of the caucate nucleus and cervical spinal cord. A case of primary lymphoma of the cerebellum is presented with review of literature.

A congenital neoplasm arising in the central nervous system is rarely encountered, and the majority of case reports that have dealt with intracranial tumors have been divided almost equally between teratomas and various gliomas. We experienced a rare case of congenital glioblastoma multiforme encountered in a three day-old male infant who presented with hydrocephalus since birth. Post-mortem examination revealed that the tumor seemed to have originated from the right thalamic region extending centrifugally to the cerebral cortex and through the brain-stem down to the cerebellum.
