Hydatidosis can be a cause of anaphylaxis; it has been clearly established that the accidental rupture of a cyst during surgery can provoke severe anaphylactic reactions. Spontaneous anaphylaxis secondary to hydatid disease is much less frequent. ⋯ Two years after surgical resection of cysts, no new episodes of anaphylaxis have occurred. Hydatidosis is a cause of apparently spontaneous anaphylaxis and this is likely due to an IgE-mediated mechanism.
