HYDATID CYST LOCATED INTRAORBITALLY

Cystic echinococcosis (CE) is a parasitic infestation caused by the Echinococcus Granulasus tapeworm. Although adults are the most affected, children also suffer from this disease. The lungs are the most common sites of infection in children, but other sites are also affected. Orbital cystic echinococcosis is rare in children, even in endemic areas. Whether the origin of this site is primary or secondary remains controversial, particularly in children. Its left unilateral location has been reported in most publications. Diagnosis is made on the basis of anamnesis in an endemic context and imaging (ultrasound, CT and MRI), which makes a vital contribution to management and is confirmed by histological examination. We report a case of CE involving the orbit and presenting as progressively increasing exophthalmos and orbital swelling in a 5-year-old child, together with the echograrbic CT and MRI features.
