目的：探讨脉络丛乳头状瘤的CT、MRI特征并与病理进行对照分析，目的在于提高对本病的认识。方法：回顾性分析经手术及病理证实的19例脉络丛乳头状瘤的CT、MRI表现，其中5例患者行CT检查、10例行MRI检查、4例同时行CT和MRI检查，并将影像学表现与术后病理进行对照。结果：肿瘤位于四脑室13例，侧脑室5例，桥小脑角区1例；肿瘤边缘呈乳头状或分叶状18例，MRI增强后内部出现桑椹样或颗粒状强化13例；病灶内出现钙化6例，出血2例，脑积水18例。病理诊断脉络丛乳头状瘤（WHO I级）14例，非典型脉络丛乳头状瘤（WHO II级）5例。结论：脉络丛乳头状瘤的影像学表现与病理学特征密切相关，病理学基础有助于理解该病的影像学表现。

Objective:To investigate the phenotypes of choroids plexus papiloma in CT, MRI and comparatively analyze them with pathologic manifestations so as to understand this disease. Methods:A retrospective analysis of CT and MRI phenotype was applied in 19 cases of choroids plexus papilloma, confirmed by surgery and pathology, among which 5 cases were checked with CT, 10 with MRI, 4 with CT and MRI. Image finding was compared with pathological result. Results: There were 13 cases of tumor in the fourth ventricle, 5 in the lateral ventricle, 1 in cerebellum pontine angle;there were 18 cases of papillary tumor margins or ovulated, 13 cases of tumor enhancement after internal mulberry-like or granular enhanced in MRI;And there were 6 cases of tumor lesions calcification, 2 of hemorrhage, 18 of hydrocephalus. There were 14 cases of tumor diagnosis choroids plexus papilloma(grade I), 5 cases diagnosis atypical choroids plexus papilloma(II level)in pathological diagnosis. Conclusion: A close link exists in imaging performance and pathological features of choroids plexus papilloma, pathological features could help us understand imaging performance.
