Fibrous dysplasia is an uncommon benign disease of the bone, with slow progression. Monostotic involvement of the paranasal sinuses is rare. We report a 54-year-old woman who had complaints of facial asymmetry, chronic sinusitis, recurrent headaches, and nasal obstruction for two years. Conventional radiography showed opacification and expansion of the maxillary sinus. Axial and coronal computed tomography scans showed a heterogeneous mass that expanded the right maxillary sinus, leading to nasal obstruction and cortical thickening of the maxilla. No signs of destruction or erosion in the cortical bone were identified. An endonasal endoscopic biopsy was performed and the diagnosis of fibrous dysplasia was confirmed histologically.
骨纤维异常增殖症是一种罕见的、进展缓慢的骨良性疾病。鼻窦单发性受累较为罕见。我们报告一名54岁女性，她主诉面部不对称、慢性鼻窦炎、反复头痛和鼻塞两年。传统X线摄影显示上颌窦混浊和扩大。轴位和冠状位计算机断层扫描显示一个异质性肿块，该肿块使右上颌窦扩大，导致鼻塞和上颌骨皮质增厚。未发现皮质骨有破坏或侵蚀迹象。进行了鼻内镜活检，组织学检查确诊为骨纤维异常增殖症。
