Summary
Orbital hydatid cysts, caused by Echinococcus tapeworms, are exceptionally rare. This case highlights a successful surgical excision and albendazole treatment for a primary orbital hydatid cyst presenting with proptosis and diplopia.
Area of Science:
- Parasitology
- Ophthalmology
- Neurosurgery
Background:
- Hydatid cyst is a rare parasitic infection caused by Echinococcus larval stages, affecting various organs.
- Orbital hydatid cysts are extremely rare, representing less than 1% of all hydatid cysts, even in endemic regions.
Observation:
- A 24-year-old male presented with proptosis and diplopia due to a primary orbital hydatid cyst.
- MRI revealed a lesion displacing the optic nerve and globe, with characteristic signal intensities on T1 and T2 weighted images.
Findings:
- Surgical enucleation via frontotemporal craniotomy and superior orbitotomy was performed.
- Histopathological examination confirmed the diagnosis of hydatid cyst.
Implications:
- This case underscores the importance of considering rare parasitic infections in orbital pathologies.
- Successful management involves surgical excision combined with systemic albendazole therapy.
