An elderly (8th decade) diabetic patient presented with insidious, painless protrusion of the right eye for 1 month, associated with nasal congestion. Past history included healed serous chorioretinopathy in the right eye (>30 years back) and recently diagnosed (1 year prior) autoimmune IgG4-related pancreatitis for which he was on long-term corticosteroids. On nasal endoscopic examination, a well circumscribed mass was found in the right nasal cavity.Keeping in mind the systemic diagnosis, the sinonasal mass was suspected to be a IgG4-related disease. An endoscopic biopsy was performed and revealed a surprise diagnosis of grade 1 nasal schwannoma.
一位 80 多岁的老年糖尿病患者，1 个月来出现右眼进行性、无痛性突出，伴有鼻塞。既往史包括右眼浆液性脉络膜视网膜病变（30 多年前）和最近诊断的自身免疫 IgG4 相关胰腺炎（1 年前），为此他长期服用皮质类固醇。鼻内镜检查发现右侧鼻腔有一个界限清楚的肿块。考虑到全身诊断，鼻窦肿块疑为 IgG4 相关疾病。进行了内镜活检，结果出乎意料地诊断为 1 级鼻腔神经鞘瘤。
