Summary
Orbital hydatidosis is a rare condition causing eye proptosis. Early diagnosis and surgical removal are key, with medication potentially needed if the cyst ruptures during surgery.
Area of Science:
- Ophthalmology
- Parasitology
- Radiology
Background:
- Orbital hydatidosis is an uncommon parasitic infection, representing only 1% of all hydatid cysts.
- This condition typically affects the orbit, presenting as a rare cause of proptosis.
Observation:
- A 74-year-old farmer presented with progressive proptosis and vision loss in the left eye.
- Imaging confirmed a hydatid cyst within the orbit.
Findings:
- Orbital hydatidosis is usually unilateral, often affecting the left eye, and commonly seen in younger individuals.
- Diagnosis relies on imaging (CT/MRI) due to unreliable serology; surgical resection is the primary treatment.
- Postoperative albendazole is recommended if intraoperative spillage occurs.
Implications:
- Hydatid cysts must be considered in the differential diagnosis of unilateral proptosis, especially in endemic areas.
- Prompt diagnosis and management are crucial for preserving vision and preventing complications associated with orbital echinococcosis.
