Bilateral lung and liver hydatid cysts. Case report.

Introduction. Synchronous occurrence of pulmonary and hepatic hydatid cysts is an uncommon manifestation of hydatid disease that is observed in less than 10% of cases. We report a rare case of bilateral lung (with bronchial fistula) and liver cyst, surgically treated after medical therapy. Case report. A 44-year-old housewife reporting fever, anorexia and fatigue that had been present for the previous 20 days received diagnosis of bilateral lung and liver hydatid cyst. Because of the dimensions of right lung cyst and the successive bronchial fistolization, we proceeded to three-stage operation of two thoracotomies and a laparotomy to control the risk of further rupture. After surgery, all post-operatives were uneventful. Complete resolution of the therapy with no evidence of recurrence at 2 years follow-up. Conclusion. We emphasize the need to search for additional hydatids in patients who present with either pulmonary or liver hydatids. The simultaneous treatment of liver and lung should be reserved to patients in good conditions; in all other cases, especially when one cyst is more symptomatic than the others or has more risk of rupture, we prefer to treat single cyst.
