[Anaphylactic shock caused by the rupture of an unknown hepatic hydatid cyst].
We report the case of a 66-year-old woman with moderate-to-severe mitral stenosis who survived anaphylactic shock due to traumatic rupture of a hydatid liver cyst. Hydatid liver disease was diagnosed by ultrasound, and necessary life-support measures were taken, with hydration to restore electrolytic balance and vasoactive amines. The suspected diagnosis of hydatid liver cyst rupture was confirmed surgically. We discuss the immunologic mechanisms of anaphylactic shock and its treatment, and emphasize that Echinococcus liver cysts should be suspected in cases of anaphylaxis of uncertain etiology. Acute vascular collapse, generalized cutaneous erythema, urticaria and edema are suggestive of anaphylaxis arising from hydatidosis, particularly when patients reside in endemic areas.
