A 22-year-old woman presented with a 3-year history of progressive frontal headache. Computerized tomography (CT) and magnetic resonance imaging (MRI) revealed a tumor in the left trigone of the lateral ventricle and which enhanced homogeneously. The tumor was attached to the cerebellar tentorium and was compressing the brain stem. On the angiography, no tumor staining was seen. On November 26, 1996, total removal of the tumor was performed using the left subtemporal approach. The tumor was attached to the cerebellar tentorium. The pathological diagnosis was mesenchymal chondrosarcoma. After surgery, gamma-knife radiosurgery was carried out on the tentorium at the place where the tumor had been attached. There has been no recurrence for 6 months. Mesenchymal chondrosarcoma in the brain is very rare and therapy for this tumor is difficult. We report this rare tumor and the therapy is discussed.
一名22岁女性，有3年进行性额部头痛病史。计算机断层扫描（CT）和磁共振成像（MRI）显示侧脑室左三角区有一肿瘤，呈均匀强化。肿瘤附着于小脑幕，压迫脑干。血管造影未见肿瘤染色。1996年11月26日，采用左颞下入路将肿瘤完全切除。肿瘤附着于小脑幕。病理诊断为间叶性软骨肉瘤。术后，对肿瘤附着部位的小脑幕进行了伽玛刀放射外科治疗。6个月来未见复发。脑内间叶性软骨肉瘤非常罕见，该肿瘤的治疗也很困难。我们报告了这一罕见肿瘤并讨论了其治疗方法。
