Summary
Sphenoid sinus mucoceles can cause recurrent vision problems. This case highlights the importance of considering posterior paranasal sinus mucoceles in the differential diagnosis of unilateral visual disturbances.
Area of Science:
- Otolaryngology
- Neurology
- Ophthalmology
Background:
- Recurrent unilateral visual disturbance can present diagnostic challenges.
- Sphenoid sinus mucoceles are rare benign cysts that can cause various symptoms due to mass effect.
Observation:
- A 22-year-old female experienced two episodes of left-sided visual disturbance over three months.
- Initial diagnosis was acute retrobulbar optic neuritis, treated successfully with corticosteroids.
- MRI revealed a left sphenoid sinus mucocele; optic canal showed no destruction but the optic nerve exhibited T2-weighted high intensity suggesting swelling.
Findings:
- The visual disturbance pathogenesis was attributed to optic canal inflammation or edema, not direct compression by the mucocele.
- The recurrent nature and unilateral presentation were key diagnostic clues.
Implications:
- This case underscores the necessity of including posterior paranasal sinus pathology, specifically sphenoid sinus mucoceles, in the differential diagnosis for recurrent unilateral visual disturbances.
- Early identification and management of sphenoid sinus mucoceles can prevent permanent visual impairment.
