Unilateral exophthalmos in orbital echinococciasis

Area of Science:

• Ophthalmology
• Radiology
• Parasitology

Background:

• Hydatid cysts are typically found in the liver and lungs, rarely occurring in the orbit.
• Orbital hydatidosis can lead to vision impairment and requires accurate diagnosis for effective treatment.

Observation:

• A patient presented with symptoms suggestive of an orbital mass.
• Computed tomography (CT) revealed a cystic lesion in the right orbit consistent with a hydatid cyst.

Findings:

• The imaging characteristics on CT were definitive for a hydatid cyst.
• Surgical or medical management of the parasitic infection was indicated.

Implications:

• This case underscores the need for considering parasitic etiologies in orbital cystic lesions.
• Accurate CT diagnosis facilitates timely and appropriate management of orbital hydatid disease.
• Awareness of this rare presentation is crucial for ophthalmologists and radiologists.
