We present a case of sphenoid sinus mucocele with recurrent visual disturbance on the same side. A 22-year-old female showed two episodes of visual disturbance in the left eye for 3 months, and acute retrobulbar optic neuritis was diagnosed. With corticosteroid, visual disturbance improved in 1 week. MRI and CT scans showed mucocele in the left sphenoid sinus, and left optic nerve swelling with high intensity was observed in T2-weighted MRI. No destruction of the optic canal was found. The contiguous inflammation in the optic nerve rather than compression was considered as pathogenesis.
我们报告一例蝶窦黏液囊肿伴同侧复发性视觉障碍的病例。一名22岁女性在3个月内出现了两次左眼视觉障碍，被诊断为急性球后视神经炎。使用皮质类固醇治疗后，视觉障碍在1周内有所改善。MRI和CT扫描显示左侧蝶窦有黏液囊肿，T2加权MRI上观察到左侧视神经肿胀且信号强度高。未发现视神经管破坏。视神经的连续性炎症而非压迫被认为是发病机制。
