[Malignant hydatid disease--clinical case].

We report the case of a 79-year-old woman admitted for sepsis from a hepatic hydatid cyst with multiple disseminations diagnosed one month earlier who refused the surgical treatment. Her family history was irrelevant with regard to the circumstances leading to Taenia Echinococcus infestation, and given her poor health status and absence of previous medical documents no useful information was obtained from her medical history. The patient also presented chronic ischemic heart disease and anemia secondary to a bleeding duodenal ulcer, found at necropsy, which worsened the already unfavorable course by the acute hepatic and renal failure secondary to toxic and septic shock. Despite the complex treatment, death occurred 6 days later, following a second episode of upper digestive hemorrhage. Particular to this case is the absence in patient's history of the anaphylactic/allergic reactions suggestive of hepatic hydatid cyst dissemination.
