Abstract：
Ethmoidal sinus mucoceles are benign expansile lesions that may progressively invade the orbit causing optic nerve compression and its nearby structures. We report a rare case of primary ethmoidal sinus mucocele instigating orbital apex syndrome. A 40-year-old man presented with right eye (RE) progressive blurring of vision with diplopia for 2 weeks. It was preceded by right-sided facial pain for 3 months. Clinical examination revealed RE proptosis with multiple cranial nerves palsy involving right cranial nerves II, III, IV, V, and VI, suggestive of right orbital apex syndrome. Magnetic resonance imaging (MRI) demonstrated right eye proptosis and right ethmoidal mucocele with intracranial and right intraorbital extension compressing the right medial rectus and optic nerve. The patient underwent an uncomplicated endoscopic sinus surgery resulting in a return to normal appearance and function post-operation. Thus, ethmoidal mucoceles are benign and curable with early recognition and intervention.
摘要：
筛窦黏液囊肿是良性扩张性病变，可能逐渐侵入眼眶，导致视神经受压及其附近结构。我们报告了一例罕见的原发性筛窦黏液囊肿引起眶尖综合征。一名40岁的男子出现右眼（RE）进行性视力模糊并复视2周。之前出现右侧面部疼痛3个月。临床检查显示RE突增伴累及右颅神经的多个颅神经麻痹II，III,IV,V,VI,提示右眶尖综合征。磁共振成像（MRI）显示右眼眼球突出和右筛黏液囊肿，颅内和右眶内延伸压迫右内侧直肌和视神经。患者接受了简单的内窥镜鼻窦手术，导致术后恢复正常的外观和功能。因此，筛骨黏液囊肿是良性的，可通过早期识别和干预治愈。
