We report a rare case of intradural primary osteosarcoma (IPOS) in a 74-year-old man with aphasia and right-sided hemiparesis. Radiologic workup revealed a large, partially calcified, left-sided frontotemporal intracranial mass lesion. At surgery, the tumor was found to be entirely intradural; it involved the brain and subarachnoid space of the left sylvian fissure. The adjacent dura was uninvolved. Neuropathologic findings confirmed the diagnosis of chondroblastic osteosarcoma. To our knowledge, this is the sixth reported case of IPOS and the first reported case of the chondroblastic subtype.
我们报告了一例罕见的硬脊膜内原发性骨肉瘤（IPOS），患者为一名74岁男性，伴有失语和右侧偏瘫。影像学检查发现左侧额颞部颅内有一个大的、部分钙化的肿块病变。手术中发现肿瘤完全位于硬脊膜内；它累及左侧外侧裂的脑和蛛网膜下腔。相邻的硬脑膜未受累。神经病理学检查结果证实为软骨母细胞性骨肉瘤。据我们所知，这是第六例报告的IPOS病例，也是第一例报告的软骨母细胞亚型病例。
