The most common primary tumors of the cerebellopontine angle are growths of the 8th cranial nerve. The occurrence of other tumors in this area is very rare and may cause neuroradiological misinterpretation. We report the findings in a 37-year-old male patient suffering from a primitive neuroectodermal tumor (PNET) extending from the latero-basilar cerebellar hemisphere into the cerebellopontine angle (CPA) and causing cerebellar dysfunction as well as symptoms of typical cerebellopontine angle lesions. Differential diagnosis of tumors found in this area is given as well as a histological description of the tumor along with immunohistochemical findings and aspects of possible prognostic relevance.
桥小脑角最常见的原发性肿瘤是第8颅神经的肿瘤。该区域出现其他肿瘤的情况非常罕见，可能会导致神经放射学误诊。我们报告了一名37岁男性患者的病例，该患者患有原始神经外胚层肿瘤（PNET），肿瘤从基底外侧小脑半球延伸至桥小脑角（CPA），导致小脑功能障碍以及典型的桥小脑角病变症状。文中给出了该区域肿瘤的鉴别诊断，以及肿瘤的组织学描述、免疫组化结果和可能与预后相关的方面。
