Summary
A rare case of bilateral dynamic proptosis caused by frontoethmoidal mucoceles was successfully treated with surgical intervention. This condition, involving pulsating eye protrusion, highlights the importance of prompt diagnosis and management of sinus mucoceles.
Area of Science:
- Ophthalmology
- Neurosurgery
- Otorhinolaryngology
Background:
- Frontoethmoidal mucoceles are rare benign tumors that can cause significant orbital and intracranial complications.
- Spontaneous dynamic proptosis is an uncommon presentation of orbital pathology.
Observation:
- A 34-year-old male presented with bilateral, pulsatile, dynamic proptosis and globe displacement.
- Imaging revealed bilateral frontoethmoidal mucoceles eroding the orbital roof with intracranial extension.
Findings:
- Surgical decompression via transcutaneous mini-trephine of the left orbital mucocele resolved the dynamic proptosis.
- Significant improvement in proptosis and ocular motility was observed in the left eye post-procedure.
Implications:
- This case is the first to report frontoethmoidal sinus mucocele causing bilateral spontaneous dynamic proptosis.
- Highlights the need for considering mucoceles in the differential diagnosis of dynamic proptosis.
- Emphasizes the efficacy of surgical management for resolving such complex orbital-cranial presentations.
