This study presents a systematic review of reported cases of orbital HCs. Methods A systematic review of the published studies of orbital HCs was conducted, the studies that met the following criteria were included: 1) The presence of the infection was confirmed through diagnostic methods, surgical findings, or histopathology. 2) The study provided a detailed case presentation. Results Thirty-two studies (56 cases) met the inclusion criteria. Ten patients were from Afghanistan (17.9%). There was no gender predilection, the distribution was almost equal. The ages ranged from three to 80 years old. The most common symptoms that the patients presented with were proptosis of the affected eye (98.2%) and visual impairment (64.3%). The therapeutic approach of orbital HC was primarily surgical removal of the cyst accompanied by anthelmintic drugs in 41 (73.2%) cases. Concurrent HC was reported in two cases (3.6%), and recurrence with subsequent recovery was reported in four (7.1%) cases. Conclusion Orbital HC is a rare condition, primarily diagnosed using MRI, with surgery as the definitive treatment. Concurrent hydatidosis increases the risk of recurrence, requiring thorough and ongoing follow-up.
