脉络丛乳头状瘤影像学诊断及临床治疗研究

目的探讨脉络丛乳头状瘤的CT、MRI表现及临床治疗方法。方法回顾性分析我院收治的28例经术后病理证实为脉络丛乳头状瘤（包括1例不典型者）患者的临床资料。本组病例术前均行CT、MRI检查。结果肿瘤位于侧脑室者19例，位于第四脑室者7例，位于第三脑室者2例；所有患者均行显微手术治疗，肿瘤完全切除22例，部分切除6例（术后均行放射治疗）。术后5个月至5年，随访平均3．2年，21例治愈，4例复发，2例死亡，1例失访。结论MRI常呈颗粒状混杂信号且浸泡于脑脊液中为脉络丛乳头状瘤典型的影像学表现；手术切除是目前其首选治疗措施；放射治疗是未全切除者术后的主要辅助治疗手段。

Diagnosis of Choroid plexus papilloma by imaging and its treatment (report of 28 cases)

Objective To explore diagnosis of the choroid plexus papilloma （CPP） by imaging and its treatment. Methods The clinical data of 28 patients with CPP, who underwent microsurgery from January, 2002 to January 2012, were analyzed retrospectively, including the imaging data, therapeutic method and prognosis. All the patients received CT and MRI examination before the surgery. Results Of 28 patients, 19 had the lateral ventricle tumors, 7 the fourth ventricle tumors, and 2 the third ventricle tumors. The tumors were totally removed in 22 patients, and partly in 6. The radiotherapy was performed after the surgery in 6 patients with residual tumors. All the patients were followed up from 5 to 60 months. CPP recurred in 4 patients and 2 patients died during the following up. Conclusions The granular mixed signals soaked in the cerebrospinal fluid are typical findings on cerebral MRI in the patients with CPP, in whom, the surgical resection should be selected firstly. The radiotherapy should be performed after the surgery in the patients with residual CPP.
