颅内肿瘤是一种常见病,它的发病率仅次于胃、子宫、乳腺、食管的肿瘤,其平均年发生率约为10/10万人口。颅内各种组织,如脑、脑膜、垂体、脑神经及胚胎残余组织等均可发生肿瘤,其中以神经胶质细胞瘤最为多见,约占半数,其次为脑膜瘤、垂体腺瘤、听神经瘤及颅咽管瘤等。此外,从肺、子宫、消化道、乳腺、肝等处的恶性肿瘤转移至颅内约占5％,但近年有的报告颅内转移瘤高达30％。由此可见,颅内肿瘤的诊治值得重视。 Intracranial tumors are a common disease whose incidence is second only to that of the stomach, uterus, breast and esophagus, with an average annual incidence of about 10 million people. Intracranial tissue, such as brain, meninges, pituitary, brain and embryonic residual tissue tumors can occur, of which the most common glioblastoma, accounting for about half, followed by meningioma, pituitary adenoma, auditory nerve Tumor and craniopharyngioma and so on. In addition, the lung, uterus, digestive tract, breast, liver and other malignant tumors transferred to intracranial accounted for about 5%, but in recent years some reports of intracranial metastases up to 30%. Thus, the diagnosis and treatment of intracranial tumors deserve attention.
