We present 16 cases of benign extramedullary tumors of the foramen magnum region who were operated on between the years 1984 and 1992. On admission, no case was neurologically intact and over 50% had had symptoms for more than 1 year. Nine patients had erroneous diagnoses initially. CT myelography and magnetic resonance (MR) imaging were the most appropriate diagnostic tools in visualizing tumors of this region. All operations except one, were performed by the posterior approach without surgical mortality. Histopathological examination revealed 8 meningiomas, 6 neurinomas, one tuberculous abscess and one neurenteric cyst which has not been reported at this location before. Patients with minor to moderate disability on admission showed good functional results without any recurrences during follow-up.
我们报告了1984年至1992年间接受手术治疗的16例枕骨大孔区良性髓外肿瘤患者。入院时，无一例患者神经系统功能完好，超过50%的患者症状持续时间超过1年。9例患者最初诊断有误。CT脊髓造影和磁共振成像（MR）是可视化该区域肿瘤最合适的诊断工具。除1例手术外，所有手术均采用后路进行，无手术死亡病例。组织病理学检查显示8例脑膜瘤、6例神经鞘瘤、1例结核性脓肿和1例神经肠囊肿，该部位此前未见报道。入院时轻度至中度残疾的患者功能恢复良好，随访期间无复发。
