Intracranial chondroma is a rare benign tumor. Here, we present the case of a 29-year-old female who was afflicted with left eye blindness and ptosis. Brain computerized tomography and magnetic resonance imaging revealed the presence of a giant calcified mass accompanied by a solid mass in the middle and posterior fossa. A differential diagnosis regarding chordoma, chondrosarcoma, and other chondroid tumors based on radiologic information was inconclusive. The lesion was resected completely under a microscope using a combined pterional and subtemporal approach. The pathologic report confirmed the diagnosis of chondroma. No evidence of neurological worsening was observed. The tumor had a calcified mass with mature hyaline cartilage surrounded by a thick fibrous capsule. We dissected the periphery of the tumor mass and removed it via aspiration. It was readily distinguished from normal brain parenchymal tissue. The large calcified mass at the center of the tumor had relatively high vascularity, and a high-speed drill and various rongeurs were used to remove the tumor.
颅内软骨瘤是一种罕见的良性肿瘤。在此，我们报告一例29岁女性患者，她患有左眼失明和上睑下垂。脑部计算机断层扫描和磁共振成像显示在中后颅窝存在一个巨大的钙化肿块并伴有一个实性肿块。基于放射学信息对脊索瘤、软骨肉瘤和其他软骨样肿瘤进行的鉴别诊断尚无定论。采用翼点联合颞下入路在显微镜下将病变完全切除。病理报告证实为软骨瘤。未观察到神经功能恶化的迹象。肿瘤有一个钙化肿块，周围是成熟的透明软骨，外包一层厚厚的纤维包膜。我们解剖了肿瘤块的周边并通过抽吸将其取出。它很容易与正常脑实质组织区分开来。肿瘤中心的大钙化肿块血管相对丰富，使用高速钻和各种咬骨钳来切除肿瘤。
