Meningiomas are usually benign tumors that are frequently encountered in the intracranial region. They account for 15% of the overall intracranial tumors. Of the intracranial meningiomas, less than 3% extend up to the sinonasal region. The frequency of meningioma in females is 2 times higher than that in males; it is most commonly observed in the fifth decade of life. It is usually asymptomatic and detected incidentally. A small number of meningiomas may cause some symptoms including seizure attacks and cranial nerve paralysis according to their locations. On the physical examination of a 56-year-old woman, who presented with nasal obstruction, a mass that completely obliterated the left nasal passage was detected. An incisional biopsy finding of the mass revealed meningioma, and the patient was hospitalized in the clinic for surgical procedure. The mass was excised by endonasal endoscopic method. In this present article, we aimed to discuss a quite rare case, which had meningioma arising from the anterior skull base and completely obliterating the left nasal passage with the coexistence of right nasal polyp, in the light of the current literature.
脑膜瘤通常是良性肿瘤，在颅内区域较为常见。它们占颅内肿瘤总数的15%。在颅内脑膜瘤中，不到3%会延伸至鼻窦区域。女性患脑膜瘤的频率是男性的2倍；最常见于50岁左右。它通常无症状，多为偶然发现。少数脑膜瘤根据其位置可能会引起一些症状，包括癫痫发作和颅神经麻痹。在对一名56岁出现鼻塞的女性进行体格检查时，发现一个完全堵塞左鼻道的肿物。肿物的切开活检结果显示为脑膜瘤，患者因此在诊所住院准备接受手术。该肿物通过鼻内镜方法切除。在本文中，我们旨在结合当前文献讨论一个非常罕见的病例，该病例为前颅底脑膜瘤，完全堵塞左鼻道，同时并存右鼻息肉。
