Background: Echinococcosis represents one of the most common human parasitoses in some geographical areas. Orbital involvement is extremely rare.

Materials And Methods: In the records of our Medical University Centre between 1984 and 2006, we found 10 cases of orbital hydatid cyst.

Results: Among them, 6 males and 4 females; the ages ranged from 2 to 60 years and 7 cases (70%) were less than 12 years of age. The main symptoms of orbital hydatid cyst were slowly progressive unilateral proptosis (100%) with visual loss (90%). The presumptive diagnosis was made on the images obtained from computed tomography and/or magnetic resonance imaging. Surgical removal was the main treatment; although, it is frequently complicated with cyst rupture and spillage of the contents. For this reason, we adopted the technique of cyst puncture with irrigation. A postoperative antihelminthic treatment has always been used.

Conclusion: Hydatid cyst is an endemic disease in Morocco. Orbital involvement should be considered in the differential diagnosis of proptosis especially in children known to have been in affected geographical areas.

Article Synopsis
  • - Hydatid cysts, caused by the parasite Echinococcus granulosus, are common in many regions but instances of cerebral hydatid cysts extending to the orbit are very rare.
  • - These cerebral cysts can be either primary or secondary, and their clinical symptoms can be vague, making imaging techniques like CT and MRI essential for accurate diagnosis.
  • - The primary treatment for cerebral and orbital hydatid cysts is surgery, and the article discusses a case with unique imaging findings that help distinguish it from other similar medical conditions.

Purpose: To present a simple transconjunctival technique for the excision of intraconal orbital hydatid cysts.

Methods: This retrospective, non-comparative, clinical intervention case study was conducted between April 2018 and October 2023. The study included five patients presented to the Orbital unit of Assiut University Hospital with an intraconal orbital cyst, which histologically proved to be a hydatid cyst.

Purpose: This study aims to underscore the rarity of intraorbital hydatid disease caused by Echinococcus granulosus, emphasizing the importance of comprehensive exploration and documentation for effective management.

Observations: Clinical presentations include proptosis, visual deterioration, ocular motility disruptions, and chemosis. A case study of an 8-year-old boy with a retroorbital hydatid cyst successfully resected through a right transcaruncular orbitotomy approach is presented, highlighting surgical complexities and the efficacy of pre and post-operative albendazole therapy.
