Olfactory neuroblastomas are malignant, neuroectodermal nasal tumours. We describe a 62-year-old patient with a recurrent olfactory neuroblastoma invading a radiation-induced meningioma. Given the temporal and spatial relationship between the primary lesion and the described recurrence, this was due to metastatic rather than direct contiguous spread, fulfilling all the criteria for true tumour-to-tumour metastasis. To our knowledge, this is the first description of an olfactory neuroblastoma metastasising to a meningioma.
嗅神经母细胞瘤是一种恶性、神经外胚层鼻腔肿瘤。我们描述了一例 62 岁患者，其复发性嗅神经母细胞瘤侵犯了放射性脑膜瘤。鉴于原发性病变和所述复发之间的时间和空间关系，这是由于转移而不是直接连续扩散引起的，符合真正肿瘤对肿瘤转移的所有标准。据我们所知，这是首例嗅神经母细胞瘤转移至脑膜瘤的描述。
