A very unusual case of olfactory groove meningioma with recurrence extending into the paranasal sinuses and nasal cavities, 15 years after the first transcranial operation, is described. The patient was successfully treated by a combined subfrontal and nasal approach. Large downward extension of an olfactory groove meningioma into the nasal cavities is a rare event, with no or isolated cases reported even in large series of these tumours. The nasal extent of these meningiomas is more often asymptomatic, although signs of sinus obstruction and epistaxis have been described. Although small paranasal sinus extensions of the meningioma may be removed by the transcranial route, a combined subfrontal and nasal approach is necessary in cases with large tumour masses extending into the nasal cavities, as in our own one.
本文描述了一例非常罕见的嗅沟脑膜瘤病例，在首次经颅手术后15年复发并延伸至鼻窦和鼻腔。患者通过额下入路和鼻入路联合手术成功治愈。嗅沟脑膜瘤向下大量延伸至鼻腔是一种罕见情况，即使在大量此类肿瘤病例系列中也未报告或仅有个别病例。这些脑膜瘤在鼻腔内的范围通常无症状，尽管曾有鼻窦阻塞和鼻出血的症状描述。虽然脑膜瘤向鼻窦的小范围延伸可通过经颅途径切除，但对于肿瘤肿块大量延伸至鼻腔的病例，如我们的这例患者，额下入路和鼻入路联合手术是必要的。
