Sphenoid sinus mucocele masquerading as retrobulbar optic neuritis: a case report

摘要

>Objective: To describe an infrequent instance of sphenoid sinus mucocele presenting as retrobulbar optic neuritis and highlight the value of imaging in the diagnosis and treatment plans.>Methods: A woman aged 26 noted a sub-acute decrease in vision in the right eye, which mimicked optic neuritis. Magnetic resonance imaging (MRI) indicated a large mass in the sphenoid sinus, which was in favor of mucocele. >Results: Endoscopic sphenoidotomy and marsupialization of the mucocele were carried out, and the diagnosis was confirmed by pathology. The patient was also administered a high dose of corticosteroid, upon which progression of the disease was halted. Unfortunately, no significant improvement in vision was achieved.>Conclusions: This report emphasized the important role of imaging in differentiating between different causes of optic neuropathies. A high level of clinical skepticism along with appropriate imaging studies can help diagnose rare causes. With timely management, gratifying results may be achieved.
