Paranasal sinus mucoceles are epithelium-lined cystic masses usually resulting from obstruction of sinus ostia. They most frequently occur in the frontal and ethmoid sinuses. While ophthalmologic symptoms are most common, patients also report rhinological or neurological complaints. The close proximity of paranasal sinus mucoceles to the orbit and skull base predisposes the patient to significant morbidity. Computed tomography displays a non-enhancing homogenous mass with expansion of bony walls. Magnetic resonance imaging reveals variable intensity of T1-weighted images and a hyperintense mass on T2-weighted images. Histopathologically mucoceles have features of respiratory mucosa with areas of reactive bone formation, hemorrhage, fibrosis, and granulation tissue. Surgical excision is the standard treatment with trends towards endoscopic techniques.
鼻窦黏液囊肿是内衬上皮的囊性肿物，通常由鼻窦开口阻塞引起。它们最常发生于额窦和筛窦。虽然眼科症状最为常见，但患者也会报告鼻科或神经科方面的不适。鼻窦黏液囊肿与眼眶和颅底位置邻近，易使患者出现严重的发病情况。计算机断层扫描显示为一个无强化的均匀肿物，伴有骨壁扩张。磁共振成像显示T1加权图像强度可变，T2加权图像上为高信号肿物。组织病理学上，黏液囊肿具有呼吸黏膜的特征，伴有反应性骨形成、出血、纤维化和肉芽组织区域。手术切除是标准治疗方法，目前有采用内镜技术的趋势。
