The increased use of neuro-imaging techniques, as well as various environmental factors, has been changing the incidence and the proportions of types of intracranial tumors. However, no accurate population-based epidemiological study of intracranial tumors in Japan has been reported. We evaluated recent trends in the occurrence of primary intracranial tumors among residents of Kumamoto prefecture, Japan. METHODS AND
We surveyed 5,448 new cases of primary intracranial tumors that were diagnosed in Kumamoto prefecture between 1989 and 2008. The overall age-adjusted incidence rate was 14.09 (11.59 for males, 16.38 for females) per 100,000 population per year. The most common tumors were meningiomas (36.8%), followed by gliomas (19.5%), adenomas (17.8%), schwannomas (9.9%), and malignant lymphomas (3.6%). The number of cases of primary brain tumors, especially meningiomas and malignant gliomas, among the elderly has steadily increased and the incidence of asymptomatic intracranial tumors also increased. The number of asymptomatic meningiomas diagnosed per year was higher than that of symptomatic meningiomas in the years between 1997 and 2008. Furthermore, the incidence rate of brain lymphoma in Kumamoto prefecture is approaching that recorded in Western countries. On the other hand, the incidence rate of germ cell tumors is on the decline, approaching that recorded for children in Western countries.
Even though we adjusted the population in Kumamoto prefecture based on the Japanese population, increasing rates of several types of intracranial tumors were observed. These incidence rates are approaching those in Western countries.

Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)
Glioma derived from ependymocytes that tend to present as malignant intracranial tumors in children and as benign intraspinal neoplasms in adults. It may arise from any level of the ventricular system or central canal of the spinal cord. Intracranial ependymomas most frequently originate in the FOURTH VENTRICLE and histologically are densely cellular tumors which may contain ependymal tubules and perivascular pseudorosettes. Spinal ependymomas are usually benign papillary or myxopapillary tumors.

Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain.
A benign tumor of the nervous system that may occur sporadically or in association with VON HIPPEL-LINDAU DISEASE. It accounts for approximately 2% of intracranial tumors, arising most frequently in the cerebellar hemispheres and vermis. Histologically, the tumors are composed of multiple capillary and sinusoidal channels lined with endothelial cells and clusters of lipid-laden pseudoxanthoma cells. Usually solitary, these tumors can be multiple and may also occur in the brain stem, spinal cord, retina, and supratentorial compartment. Cerebellar hemangioblastomas usually present in the third decade with INTRACRANIAL HYPERTENSION, and ataxia. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2071-2)
