Choroid plexus papillomas (CPP) are rare tumors of the central nervous system, usually occurring in the ventricular system. Apart from spinal drop metastases, CPPs are generally unique tumors. In this report, the authors present two exceptional adult cases involving multiple benign CPPs located in both intra- and extraventricular locations. The tumors were located in the fourth ventricle and Meckel's cave in one case and the cerebellopontine angle, the frontotemporal region and the fourth ventricle in the other. A review of the literature revealed that these two cases represent the first reported occurrences of multiple choroid plexus papillomas involving Meckel's cave and frontotemporal intraparenchymal locations.
脉络丛乳头状瘤（CPP）是一种罕见的中枢神经系统肿瘤，通常发生在脑室系统。除了脊髓转移外，CPP 通常是独特的肿瘤。在本报告中，作者介绍了两个特殊的成人病例，涉及位于脑室内外的多个良性 CPP。一个病例的肿瘤位于第四脑室和 Meckel 氏腔，另一个病例的肿瘤位于桥小脑角、额颞叶区域和第四脑室。文献复习显示，这两个病例代表了首例报道的累及 Meckel 氏腔和额颞叶脑实质内的多个脉络丛乳头状瘤。
