[Orbital echinococcosis with two different features; hydatid and alveolar cysts]

ABSTRACT

To present two patients with hydatid and alveolar cysts of the orbit and to present their clinical, imaging, pathologic and therapeutic features. Two young children from rural areas were referred for progressive proptosis. Imaging showed intraorbital cysts. They were operated on with a clinical suspicion of hydatid and alveolar cysts. Pathologic evaluation confirmed the diagnoses in both instances. Clinical findings and imaging before the operation help the diagnosis of orbital echinococcosis. Knowing the nature of these lesions can prevent surgical complications. Alveolar cysts are much more invasive than hydatid cysts and their treatment is more difficult
