Isolated hydatid cyst in the medial rectus muscle: unveiling a rare orbital occurrence.

Orbital hydatid disease, while rare, should be included in the differential diagnosis of unilateral proptosis, particularly in endemic areas. Accurate diagnosis and comprehensive management are essential for effective treatment and favorable long-term outcomes. A 12-year-old boy presented with a one-month history of diplopia and left-sided proptosis. A CT scan revealed a cystic mass within the left medial rectus muscle. Surgical intervention confirmed the presence of a hydatid cyst following cyst rupture and irrigation with hypertonic saline. The patient underwent a two-month course of albendazole therapy. Initially, the patient experienced persistent exotropia and diplopia, but at the three-year follow-up, he exhibited no diplopia or proptosis and only mild residual exotropia. This case underscores the importance of considering orbital hydatid cysts in the differential diagnosis of unilateral proptosis in endemic regions. Heightened awareness, accurate diagnosis, and a tailored therapeutic approach, including surgical removal and antiparasitic treatment, are crucial for successful management and improved long-term outcomes.

A simple transconjunctival technique for the management of intraconal orbital hydatid cyst

Abstract 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. In all cases, a conjunctival incision near the fornix was made depending on the cyst location as revealed by computed tomography (CT) or magnetic resonance imaging (MRI). A traction suture was applied to the two relevant recti muscles to guide the globe toward the desired direction. Blunt orbital dissection was made toward the cyst until exposing its anterior surface. A 20-gauge needle was introduced into the cyst and followed by aspiration of its content. The collapsed cyst was then removed by non-toothed forceps and followed by copious irrigation of the field. The follow-up period ranged from 11 to 58 months. Results: The age of patients ranged from 11 to 44 years. Three were males and two were females. The cyst was iso-dense to the vitreous on CT and iso-intense to the vitreous on MRI. In all cases after aspiration of the content, the collapsed cyst was easily removed. None of the five patients developed recurrence during the follow-up period. Conclusion: The removal of the collapsed orbital hydatid cyst in the intraconal space after the aspiration of its content via transconjunctival anterior orbitotomy is a simple, fast technique with early recovery and maximum cosmesis.

Primary Intra-Orbital Hydatid Cyst in a Child: A Case Report

Hydatid disease is a tapeworm parasitic infection caused by Echinococcus Granulosus that commonly affects the liver and the lungs, during its life cycle in the human body. Orbital involvement is a very rare occurrence and isolated orbital Echinococcosis is extremely rare. We report the case of an 8-year-old moroccan girl diagnosed with an orbital hydatid cyst, which was surgically treated, the diagnosis was initially done and CT and MRI, and it was confirmed with a post-op biopsy.

ORBITAL HYDATID CYST IN A PAEDIATRIC PATIENT - A RARE CASE REPORT WITH REVIEW OF LITERATURE

Hydatid cysts are commonly confined to the liver, lungs and rarely in the central nervous system, whereas localisation of hydatid cysts in the orbit are quite rare, accounting for less than 0.8 to 1% of all the cases. It is one of the rarest causes of proptosis even in endemic areas caused by dog tapeworm, Echinococcus granulosus. Definitive treatment is surgical excision, however complete removal is many times difficult. Present study discusses a case of a 12-year-old child who presented with a progressive proptosis of the left eye and was diagnosed with orbital hydatid cyst on histopathological examination.

Orbital Hydatid Cyst: An Interventional Case Series

Purpose: To find out the demographics, presentation, and outcome of surgical treatment in patients of orbital hydatid cyst.
 Study Design: Interventional case series.
 Place and Duration of Study: Khyber Teaching Hospital Peshawar, Pakistan from 2009 to 2019.
 Methods: This study included 11 patients with orbital hydatid cyst who presented in Khyber Teaching Hospital, Peshawar. Detailed history, ocular examination and Orbital imaging (Ophthalmic B-Scan, CT scan and/or MRI) was performed. The patients underwent Orbitotomy, cyst extirpated and sent for histopathology. Albendazole was given to the patients for 12 weeks after surgery. The preoperative and postoperative data until last follow-up was analyzed.
 Results: Male to Female ratio was 5:6 and the mean age of the patients was 18.17 ± 17.4 years. Mean amount of proptosis was 26.27 ± 2.05mm and visual acuity was 0.23 ± 0.33 decimal in the affected eye at presentation. Eight patients (72.8%) had Relative Afferent Pupillary Defect with swollen discs. After imaging studies, presumptive diagnosis of hydatid cyst was made. Histopathology confirmed the diagnosis of hydatid cyst in all cases. Mean proptosis at the last follow up improved to 19.04 ± 1.45mm (P value = 0.00) and visual acuity to 0.47 ± 0.22 decimals (P value = 0.048). Only one patient (9.1%) had an associated hydatid cyst in the lung. There was no recurrence until last follow-up.
 Conclusion: Hydatid cyst should be considered in differential diagnosis of proptosis in patients under 20. Surgical excision followed by a course of oral Albendazole is effective for the treatment of orbital hydatid cyst.
 Key Words: Orbital hydatid cyst, Proptosis, Orbitotomy.

Calcified hydatid cyst of the orbit

The authors report a case of calcified cystic hydatid disease of orbit and its classical management. A 13-year-old female patient presented with unilateral progressive non-pulsatile proptosis of the right eye. Ocular examination revealed proptosis of the right eye, associated with reduced (poor) vision. In morocco as an endemic country, the orbital hydatid cyst should be considered as a differential in a child patient presenting with unilateral proptosis living in animal breeding areas.

Successful eradication of a large orbital hydatid cyst without rupture using fronto-orbitozygomatic approach, the first case reported from Syria

Hydatid disease is a parasitic infection resulted by Echinococcus granulosus in the larval stage and is most prevalent in the Middle East, India, Africa, South America, New Zealand, Australia, Turkey and Southern Europe. However, orbital hydatid cysts are rare and represent a challenge to the surgeon to eradicate the cyst without rupture. Here, we report a case of a relatively large primary intraconal orbital cyst in a 21-year-old woman. We managed to eradicate the cyst without any complication using fronto-orbitozygomatic approach, and the patient remained disease free after the 3 months of follow-up.

A Rare Case of Orbital Hydatid Cyst

Background: Cystic echinococcosis, also known as hydatid disease, which is mostly caused by larval stage of Echinococcusgranulosus. The orbital localization in rare and uncommon. Preoperative diagnosis is important to prevent from complications. Case information: Here we report the case of a child admitted for chronic proptosis whose investigations concluded with an orbital hydatid cyst. Result: We describe the case of an 8-year-old child, who consulted in our ophthalmic emergency department for a painful proptosis of the right eye with a progressive decrease in visual acuity and chronic fatigue that had been evolving for 6 months. Due to this highly evocative lesion of an orbital hydatid cyst, we carried out with an ELISA and Western Blot hydatid serology which ended negative. Faced with this orbital involvement, we performed an orbital MRI which objectified two right T2-hypersignal eye cystic lesions, well-limited, exerting a mass effect on the optic nerve and responsible of a grade 2 exophthalmos. We also performed a biological assessment including hemogram, renal and hepatic function that had been normal. The patient remained under medical treatment with albendazole before and after surgery. Conclusion: Orbital involvement, although rare, should not be ignored especially when it comes to chronic proptosis with or without a visual impact in children living around dogs or breeders or in deplorable hygienic conditions.

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

To report an unusual case of orbital hydatid cyst successfully managed by surgical excision. 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. Orbital hydatid cyst should be considered as a differential in a young patient presenting with unilateral proptosis. None.

A Rare Case Series of Intraorbital Unilocular Hydatid Cysts in Pediatric Patients

Introduction: The orbital hydatidosis due to Echinococcus granulosus accounts for only less than 1% of all hydatid cysts. Here we report a case series of intraorbital hydatid cysts. Case Presentation: This retrospective investigation included two pediatric patients (4 and 13-year-old boys) who were referred because of a progressive proptosis in northwest Iran. Orbital imaging disclosed cystic intraorbital lesions in the cases. Following clinical and surgical explorations, the histopathological evaluation re-confirmed definitely the infertile unilocular hydatid cysts. Conclusions: Differential diagnoses of orbital hydatid cysts from cystic lesions should be explicitly noticed in endemic areas prior to surgery in order to avoid complications.

A difficult surgical approach for primary orbital hydatid cyst: transconjunctival medial orbitotomy

Hydatid cysts rarely appear isolated in the orbital cavity without involvement of other organs. The cysts are usually located in the retrobulbar region, and may be extraconal or intraconal. Herein we present a case of primary orbital cyst hydatid that is adjacent to the medial rectus muscle and optic nerve in the intraconal space and the difficulties during the surgical and medical treatment period.

Orbital hydatid cyst with diverse locality in the orbit and review of literatures.

to introduce five different type of orbital involvement by hydatid cyst in 8 consecutive patients. descriptive case series. Herein 8 patients with slowly progressive proptosis from 2 to 4months earlier at their first presentation are introduced. Complete ophthalmic examinations were done. Complete blood count, serologic test, ESR (erythrocyte sedimentation rate), CT scan and MRI were requested. Surgical removal of the lesions performed in all patients. The hydatid cysts found in the extraconal (2 patients) and intraconal space (3 patients), lacrimal gland (1 patient), medial rectus (1 patient) and intraosseous of orbital wall (1 patient). The diagnosis of the isolated orbital hydatid cyst without any lesion in other parts of the body was confirmed in all patients. The recurrence was not observed in any patients during 2 - 6 years follow up. Although the most common site of involvement of orbital hydatid cyst is intraconal, it can invade various locations within the orbit.

Isolated Retrobulbar Orbital Hydatid Cyst: A Rare Case Report

Isolated orbital hydatid cyst is a rare manifestation most commonly situated in superomedial and superolateral angles of orbit. We report a case of a 24 years old female with a large retrobulbar orbital hydatid cyst causing proptosis which was not associated with any cyst in other organs. USG and CT scan aids to diagnosis while surgical excision and histopathology confirms the diagnosis.

A primary orbital hydatid cyst

Echinococcosis, caused by the tapeworm Echinococcus granulosus, is an endemic zoonosis in which humans act as accidental intermediate hosts. Orbital hydatid cysts comprise 1% to 2% of all hydatid lesions. We describe a 10-year-old boy with an orbital hydatid cyst. The orbital cyst was removed totally by frontal craniotomy and orbitotomy. It should be noted that unilateral painless proptosis in patients from countries endemic for echinococcosis could be caused by an orbital hydatid cyst.

Orbital hydatid cyst

Hydatid cysts rarely appear isolated in the orbital cavity without involvement of other organs. Most of these are situated in the superolateral and superomedial angles of the orbit. Inferiorly located cysts are very uncommon. The authors report a case of a primary hydatid cyst of the orbit with inferiolateral localization. The cyst was enucleated surgically via a rhinotomy approach. This case was considered as a primary infection, because there was no previous history of hydatid disease and no findings of liver and lung cysts on radiological examination. Physicians should include orbital hydatid cyst in the differential diagnosis of unilateral proptosis. To avoid complications that might occur during surgery, the cyst can be easily removed using a gentile enucleation technique.

Primary Orbital Hydatid Cyst

ABSTRACTThe authors want to highlight the importance of clinical, radiological and histopathological evaluation in unilateral proptosis. A 17-yearold male presented with left progressive nonpulsatile proptosis, lateral gaze diplopia and decreased visual acuity. It was diagnosed as orbital hydatid cyst on CT scan and MRI. The patient was successfully operated with near total recovery of the vision. Radiological investigation showed a circumscribed cystic lesion lateral to orbit separate from the lacrimal gland. Intraoperative cysts and postoperative histopathology confirmed the primary orbital hydatid cyst.Although rare there is always a possibility of a primary hydatid in patients with unilateral proptosis, restricted eye movements and lateral decreased visual acuity. This is possible even when the Casoni's test is negative. Surgical excision with postoperative albendazole is the effective treatment for the cure of disease.
