Choroid plexus tumors are uncommon neoplasms of the central nervous system. A series of 11 cases from the Vancouver General and British Columbia Children's Hospitals, treated during the last 12 years, are reviewed. Some of the management problems commonly encountered with these tumors are discussed. Many of these tumors are associated with severe hydrocephalus at the time of diagnosis, and the perioperative management of this hydrocephalus remains a matter of some debate. The timing of and the necessity for shunting are major considerations. Large subdural fluid collections are often discovered in the postoperative period, and these occasionally cause symptoms of increased intracranial pressure. Reasons for this problem are suggested and possible steps for its prevention are proposed. The similarity between papillary ependymomas and choroid plexus papillomas has sometimes caused difficulty in pathological diagnosis. Choroid plexus carcinomas, of which there were two in this series, also present a diagnostic challenge. Differential diagnosis affects the further treatment and prognosis for the patient.
脉络丛肿瘤是中枢神经系统的罕见肿瘤。本文回顾了过去12年中在温哥华总医院和不列颠哥伦比亚儿童医院治疗的11例病例。讨论了这些肿瘤常见的一些管理问题。许多此类肿瘤在诊断时伴有严重脑积水，而这种脑积水的围手术期管理仍存在一些争议。分流的时机和必要性是主要考虑因素。术后常发现大量硬膜下积液，这些积液偶尔会引起颅内压升高的症状。文中提出了该问题的原因及预防的可能措施。乳头状室管膜瘤和脉络丛乳头状瘤之间的相似性有时会给病理诊断带来困难。本系列中有2例脉络丛癌，也带来了诊断挑战。鉴别诊断影响患者的进一步治疗和预后。
