Choroid plexus papillomas are rare central nervous system tumors, comprising less than 1% of all brain tumors. Although choroid plexus papillomas may occur at any age, 70% of patients with this neoplasm are less than 2 years of age. Choroid plexus papillomas are neuroepithelial tumors that are World Health Organization grade I or II. In contrast, the rarely encountered choroid plexus carcinoma is classified as World Health Organization grade III. Choroid plexus papillomas are more common in the infratentorial compartment in adults and the supratentorial compartment in children. Patients with choroid plexus papillomas often present with communicating hydrocephalus secondary to cerebrospinal fluid overproduction. The prognosis of these benign neoplasms is favorable, and gross total resection is frequently curative.
脉络丛乳头状瘤是罕见的中枢神经系统肿瘤，占所有脑肿瘤的比例不到1%。尽管脉络丛乳头状瘤可发生于任何年龄，但70%的该肿瘤患者年龄小于2岁。脉络丛乳头状瘤是世界卫生组织分级为I级或II级的神经上皮肿瘤。相比之下，很少见的脉络丛癌被归类为世界卫生组织III级。脉络丛乳头状瘤在成人的幕下腔和儿童的幕上腔更为常见。脉络丛乳头状瘤患者常因脑脊液过度产生而出现交通性脑积水。这些良性肿瘤的预后良好，大体全切术常常可以治愈。
