Rupture of retroperitoneal hydatid cyst into the abdominal aorta

Abstract

We report the case of a retroperltoneal hydatid cyst ruptured into the infrarenal abdominal aorta. Initial treatment consisted of marsupialization, of the cyst with patch angioplasty of the aorta. Formation of a false anaeurysm led to reoperation for placement of an aortobifemoral bypass, but the patient died postoperatively. In spite of the exceptional character of this location, diagnosis should be suggested routinely in endemic areas when a retroperitoneal mass is discovered. Treatment should be either in situ prosthetic replacement or extraanatomic exclusion bypass.
