The causes of sudden vision loss in one eye include isolated eye diseases, vascular pathologies, and optic nerve compression. This report highlights a case of parasitosis (Echinococcus granulosus) causing sudden vision loss due to optic nerve compression. To our knowledge, this is the first reported case of a hydatid cyst extending into the optic canal through opticocarotid triangle in a pediatric patient. A 12-year-old girl presented to the ophthalmologist with progressive visual deterioration over a period of 1 week. Examination revealed reduced visual acuity in her right eye. No ocular abnormality was detected on examination, cranial imaging revealed a lesion compressing the right optic nerve and the patient was referred to neurosurgery. The bright white lesion with a microscopic appearance resembling an epidermoid tumor was completely excised after aspirating the contents with transcranial access. Pathology was reported as hydatid cyst. Hydatid cysts invading the optic canal should be considered in the differential diagnosis of sudden visual loss in the pediatric age group; however, it continues to be an important health problem in developing countries. Meticulous excision of the cyst capsule without rupture ensures the success of surgical treatment.

OBJECTIVE: Hydatid cyst disease is caused by the parasite Echinococcus granulosus. It is rarely seen in the vertebral system, occurring at a rate of 0.2–1%. The aim of this study is to present 12 spinal hydatid cyst cases, and propose a new type of drainage of the cyst.METHODS: Twelve cases of spinal hydatid cysts, surgical operations, multiple operations, chronic recurrences, and spinal hydatic cyst excision methods are discussed in the context of the literature. Patients are operated between 2005 and 2016. All the patients are kept under routine follow up. Patient demographic data and clinicopathologic characteristics are examined.RESULTS: Six male and six female patients with a median age of 38.6 at the time of surgery were included in the study. Spinal cyst hydatid infection sites were one odontoid, one cervical, five thoracic, two lumbar, and three sacral. In all cases, surgery was performed, with the aim of total excision of the cyst, decompression of the spinal cord, and if necessary, stabilization of the spinal column. Mean follow up was 61.3 months (10–156). All the patients were prescribed Albendazole. Three patients had secondary hydatid cyst infection (one lung and two hepatic).CONCLUSION: The two-way drainage catheter placed inside a cyst provides post-operative chlorhexidine washing inside the cavity. Although a spinal hydatid cyst is a benign pathology and seen rarely, it is extremely difficult to achieve a real cure for patients with this disease. Treatment modalities should be aggressive and include total excision of cyst without rupture, decompression of spinal cord, flushing of the area with scolicidal drugs, and ensuring spinal stabilization. After the operation the patients should be kept under routine follow up. Radiological and clinical examinations are useful in spotting a recurrence.
