Abstract:

Meningioma is a kind of intracranial benign neoplastic disease with a high incidence in clinical practice. According to survey data, meningioma accounts for about 30% of all intracranial tumors; of which, olfactory sulci meningioma account for 8.8%. This patient had blurred vision in both eyes for 3 months. The examination of the nervous system showed that her visual acuity of both eyes decreased, and her olfactory sensation in both nasal cavities was normal. The CT examination revealed that the patient had a frontal midline suture. The magnetic resonance imaging revealed a meningioma in the olfactory sulcus of the anterior skull base. Surgical treatment was performed and there was no recurrence after six months of follow-up. The diagnosis was meningioma. The coronal incision, subfrontal and longitudinal fissure approach were selected for the surgery; the tumor was removed in blocks; the brain tissue was protected. After the tumor was completely removed, the Dura mater attached to the tumor was burned. Simpson grade Ⅱ resection was performed. After the surgery, the patient was followed up by phone; the patient could take care of herself; no sequelae were found.

摘要：

脑膜瘤是发病率较高的颅内良性肿瘤性疾病，占所有颅脑肿瘤的30%左右，其中嗅沟脑膜瘤占8.8%。本例患者双眼视物模糊3个月，神经系统查体双眼视力下降，双侧鼻腔嗅觉正常，CT检查发现患者有额中缝，核磁检查显示前颅底嗅沟脑膜瘤，行手术治疗后半年随访无复发，诊断为脑膜瘤。手术选取冠状切口，额下及纵裂入路，分块切除肿瘤并保护脑组织，完全切除肿瘤后电灼肿瘤附着的硬脑膜，simpson分级Ⅱ级切除。术后电话随访，患者生活自理，未遗留后遗症。
