Pneumatocele of the orbit
1Department of Ophthalmology, University Hospitals of Cleveland, Ohio, USA.
Purpose:
To describe an uncommon sinus condition that can cause proptosis.
Methods:
Intermittent unilateral proptosis and diplopia developed in a 29-year-old man. Computed tomography showed an enlarged frontal sinus with erosion of the floor of the sinus and air in the orbit.
Results:
Endoscopic ethmoidectomy and frontal sinusotomy corrected an outlet check valve of the nasal frontal duct and eliminated the proptosis.
Conclusion:
Pneumatocele of the orbit is an uncommon cause of proptosis and diplopia and can be corrected with endoscopic sinus surgery.
