Abstract
Hydatid disease is a parasitic infection caused by Echinococcus granulosus characterised by cyst formation in various organs. The liver is the most commonly involved organ. Hydatid disease is endemic in many parts of the world and its prevalence is also high in the Mediterranean region including Turkey. Uncomplicated liver cysts may stay asymptomatic for a long time. Hydatid cysts can rupture either spontaneously or following trauma. Anaphylaxis is an acute, life-threatening medical emergency with many potential triggers. The rupture of hydatid cysts caused by sports trauma is very rare and can lead to anaphylactic reactions and fatal anaphylaxis. We described a patient who was previously unknown to have hydatid disease being treated in the emergency setting following a sports trauma.
