This unusual case serves to demonstrate that echinococcosis, though rare, should be considered in the differential diagnosis of cystic lesions in every anatomic location, especially when they occur in endemic areas. We overview the diagnosis and treatment of this parasitic infection.

Antero-posterior distortion of the skull following such a deceleration injury can cause laceration and thrombosis of the pre-chiasmal and pial arteries supplying the optic chiasm. The ensuing ischaemic changes subsequently caused delayed softening of the chiasm and its avulsion. The concomitant retrobulbar haemorrhage and mass effect within the orbit consequently led to the partial expulsion of the globe.
