Polyp and mucocele are the commonest sinonasal tumours and schwannoma is rarely found in the paranasal sinuses. We report a case of a 64-year-old man presenting with progressive nasal obstruction and numbness on left cheek for the past 2 months. High-resolution CT found a soft tissue mass in the maxillary antrum with bony destruction. Clinical features, radiological scan and nasal endoscopic examination were suggestive of a malignant tumour. Tumour was excised through Caldwell-Luc's approach and histopathological examination found a mixed schwannoma.
息肉和黏液囊肿是最常见的鼻窦肿瘤,而神经鞘瘤在鼻窦中很少见。我们报告一例64岁男性病例,该患者在过去2个月中出现进行性鼻塞和左侧面颊麻木。高分辨率CT发现上颌窦有一个伴有骨质破坏的软组织肿块。临床特征、影像学扫描和鼻内镜检查提示为恶性肿瘤。通过柯-陆氏进路切除肿瘤,组织病理学检查发现为混合性神经鞘瘤。
