Hydatid cyst of the orbit in a young Nigerian female: a case report

Abstract

Objective: To report an unusual case of orbital hydatid cyst successfully managed by surgical excision.Case report: A 33-year-old female presented with gradual protrusion of the left eye associated with poor vision, cosmetic embarrassment and watering. She had excision biopsy of an encapsulated cystic lesion with cheesy tissue and serous content. Orbital hydatid cyst due to echinococcosis was confirmed at histopathological examination of the excised tissue. She subsequently became pregnant hence, could not undergo post-operative antihelminthic treatment, but was managed conservatively with no recurrence after five years of regular follow-up.Conclusion: Orbital hydatid cyst should be considered as a differential in a young patient presenting with unilateral proptosisFunding: NoneKeywords: Echinococcosis, Hydatid cyst, Orbit, Nigerian, Proptosis

Prevalence and distribution ofEchinococcusspp. in wild and domestic animals across Africa: A systematic review and meta‐analysis

“…In humans, studies have demonstrated 0%-3% CE prevalence in endemic regions (Assefa et al, 2015;Barclay et al, 2013;Klungsøyr, Courtright, & Hendrikson, 1993;Magambo, Hall, Zeyle, & Wachira, 1996;Magambo, Zeyhle, & Wachira, 1998;Shambesh et al, 1999) and <1% in non-endemic regions (Dada, 1980;Sixl, Rosegger, Schneeweiss, Withalm, & Schuhmann, 1987). A major challenge of CE infection in humans is the frequent misdiagnosis due to the covert clinical presentation and chronic nature of Echinococcus infection (Fasina & Ogun, 2017;Kassa, Yeshi, Abraha, & Gebremariam, 2014). Therefore, a high index of suspicion in patients visiting hospitals with unusual presentations has been suggested to guide towards identifying CE infection (Kassa et al, 2014).…”

Cystic Lesions of the Orbit

“…Common symptoms include unilateral, progressive proptosis (nontender or with mild pain/discomfort), restricted ocular motility, visual changes, and conjunctival chemosis 93,94,97 . In chronic cases, there may be compressive optic neuropathy with choroidal folds 98 . A thorough history may uncover useful diagnostic clues, such as previous infection with E. granulosus elsewhere in the body, positive serology, or a history of travel to endemic areas, particularly rural locations with exposure to dogs and/or livestock 93,96,98 …”

Clinical Case of Echinococcosis of the Orbit. Modern Approaches to Diagnosis and Treatment

“…При использовании орбитальных доступов часто в качестве интраоперационного осложнения наблюдались разрывы кисты [6,27]. Это осложнение не только может приводить к диссеминации процесса и рецидивам, но и к развитию анафилактического шока.…”

“…Известно также, что неадекватная противопаразитарная терапия может давать временное улучшение (уменьшение полостей эхинококковой кисты, уплотнение ее оболочек) с последующим развитием рецидива [26]. Пациенты с эхинококкозом глазницы обращаются за медицинской помощью, как правило, когда сформировавшийся патологический процесс требует быстрого хирургического решения и не оставляет альтернативы для длительной консервативной терапии [27].…”
