Report on an extradural meningioma of the left nasal cavity and ethmoid sinus with secondary extension into the subfrontal region in an 18-year old male. Review of 37 similar cases reported in literature. These slowly growing non-infiltrating tumours cause nasal obstruction and sinusitis but have no characteristical clinical symptoms. The origins of these tumours are obviously arachnoideal meningocytes which accompany the olfactory filaments through the lamina cribrosa to the extradural site.
一名18岁男性左鼻腔及筛窦硬脑膜外脑膜瘤继发延伸至额下区域的病例报告。对文献中报道的37例类似病例进行综述。这些生长缓慢的非浸润性肿瘤可导致鼻塞和鼻窦炎，但无特征性临床症状。这些肿瘤明显起源于蛛网膜细胞，它们伴随嗅丝穿过筛板至硬脑膜外部位。
