Ewing sarcoma and peripheral primitive neuroectodermal tumor (ES/pPNET) is an undifferentiated malignant tumor that is most prevalent in children and young adults and often radiologically mimics a meningioma. A 38-year-old female patient visited our hospital with complaints of right-sided tinnitus, right hemiparesis, and imbalance. She underwent preoperative imaging and was subsequently diagnosed as having a meningioma on the petrous ridge. After partial resection, gene fusion was confirmed, and she was diagnosed with ES/pPNET. The tumor was successfully treated using a multidisciplinary approach of adjuvant chemo- and radiotherapy. This case is noteworthy because it is an extremely rare case of an intracranial ES/pPNET, and it is worth sharing our clinical experience that the tumor was successfully treated through a multidisciplinary therapeutic approach even though complete resection was not achieved.
尤因肉瘤和外周原始神经外胚层肿瘤(ES/pPNET)是一种未分化的恶性肿瘤,在儿童和年轻人中最为常见,在放射学上常类似脑膜瘤。一名38岁女性患者因右侧耳鸣、右侧偏瘫和平衡失调前来我院就诊。她接受了术前影像学检查,随后被诊断为岩骨嵴脑膜瘤。部分切除术后,证实存在基因融合,她被诊断为ES/pPNET。通过辅助化疗和放疗的多学科方法成功治疗了该肿瘤。该病例值得注意,因为它是颅内ES/pPNET极为罕见的病例,尽管未实现完全切除,但通过多学科治疗方法成功治疗了该肿瘤,我们的临床经验值得分享。
