嗅神经母细胞瘤1例
1.32cm;CT检查:鼻咽顶后壁偏右可见大小约2.5cm×1.8cm结节状软组织,密度影CT值32.5Hu,右上颌窦腔内可见软组织密度影,二者经上颌窦孔相连,增强后强化明显且均匀,窦壁骨质未见破坏,右上颌窦腔内可见液平。诊断:鼻咽癌侵及右上颌窦。患者去中日友好医院经鼻咽镜检,病理回报:鼻咽部小细胞恶性肿瘤,考虑嗅神经母细胞瘤,免疫syn(+),clc(一),s一100(一),lca(一),考虑上颌窦为肿瘤侵犯,双颈淋巴结转移。2讨论嗅神经母细胞瘤少见,不超过鼻腔窦肿瘤的3%。Berger等于1924年首先以嗅神经上皮瘤命名,嗅神经母细胞瘤是外胚层神经上皮源性肿瘤,一般认为起源于筛骨板或鼻腔嗅区黏膜的嗅神经细胞(解剖:鼻黏膜分布嗅丝通过筛板孔到达嗅球),肿瘤多首发于鼻腔顶部或近中鼻甲处侧壁等处。早期可无明显症状,随病变发展,可出现鼻塞、嗅觉下降或丧失,可有颈部淋巴结和全身转移(属Ⅲ期),术后复发者肿瘤侵犯的范围较首次要广泛。由于嗅神经母细胞瘤cT表现缺乏特异性,易误诊为内翻性乳头状瘤、鼻咽纤维血管瘤、鼻腔癌等。①内翻性乳头状肿瘤可以通过自然孔侵入周围鼻窦,[link widoczny dla zalogowanych],但内翻性乳头状肿瘤主要以膨胀性生长为主,自然孔扩大,邻近钩突,筛房间隔常有增生、硬化;②鼻咽纤维血管瘤也可通过自然孔扩展,[link widoczny dla zalogowanych],甚至侵入眶内、颅内,但对周围骨质膨胀性骨质吸收为主,少有坏死,多起源于鼻咽顶壁,多见于15岁~30岁男性青壮年,这些与嗅神经母细胞瘤不同;③上颌窦癌可广泛浸润邻近鼻窦、眼眶,进入颅内,与嗅神经母细胞瘤类似,[link widoczny dla zalogowanych],两者难鉴别,但上颁窦癌多见于老年人,坏死更为明显,强化不如嗅神经母细胞瘤。本例肿瘤CT表现为:鼻咽顶后壁偏右侧可见大小约2.5cm×1.8cm,结节状软组织密度影,右上颌窦腔内亦可见软组织密度影,二者经上颌窦孔相连,增强后强化明显且均匀,右上颌窦腔内可见液平,窦壁骨质未见破坏。初诊:鼻咽癌侵及右上颌窦,最终经去中日友好医院鼻咽镜检病理回报,[link widoczny dla zalogowanych],考虑嗅神经母细胞瘤,免疫syn(+o总之,如果鼻腔顶部的肿瘤侵及鼻窦,具有恶性征象,有沿嗅神经蔓延趋势或破坏筛板向颅内侵犯,而坏死少、强化明显者要考虑嗅神经母细胞瘤可能,确定诊断需要依赖病理和免疫组织化学检查。
