Ewing sarcoma (ES) is an aggressive, high-grade neuroectodermal neoplasm that frequently manifests in children and young adults. Although ES without osseous involvement most commonly involves paravertebral regions of the spine, it very rarely presents as a primary intracranial tumor. This report discusses a unique presentation of an adult extraosseous ES arising from the pineal region with extension into the third and fourth ventricles and multiple drop metastases to the spine. This case demonstrates the application of current chemotherapeutic and adjuvant management and offers insight into possible treatment modalities for metastasis in an atypical extraosseous ES involving the brain and spine.
尤因肉瘤(ES)是一种侵袭性的高级别神经外胚层肿瘤,常见于儿童和青年。虽然无骨受累的ES最常累及脊柱的椎旁区域,但它极少表现为原发性颅内肿瘤。本报告讨论了一例成人松果体区骨外ES的独特表现,肿瘤延伸至第三和第四脑室,并向脊柱多发播散转移。该病例展示了当前化疗和辅助治疗的应用,并为涉及脑和脊柱的非典型骨外ES转移的可能治疗方式提供了见解。
