The authors report a rare case of benign choroid plexus papilloma arising in the cerebellopontine angle (CPA) in a 34-year-old man. Atypical features are described. This is the fourth case of MR evaluation of such tumor in available literature and the second case in the United States. Differential diagnosis is discussed. Choroid plexus papilloma should be considered among calcified, vascular, enhancing masses of CPA even in adulthood. The authors also report an unusual case of choroid plexus carcinoma.
作者报告了一例罕见的发生于一名34岁男性桥小脑角（CPA）的良性脉络丛乳头状瘤病例。文中描述了其非典型特征。这是现有文献中第四例关于此类肿瘤的磁共振成像（MR）评估病例，也是美国的第二例。文中讨论了鉴别诊断。即使在成年患者中，对于桥小脑角处钙化、血管性、强化性肿块，也应考虑脉络丛乳头状瘤。作者还报告了一例不寻常的脉络丛癌病例。
