title: An asymptomatic ruptured hepatic hydatid cyst case presenting with subdiaphragmatic gas in a traumatic patient.
abstract: Hydatid disease presents as hydatid cysts primarily in the liver and lungs. Although hepatic hydatid cysts (HHCs) may be asymptomatic for many years, they may be symptomatic due to expansion, rupture, and pyogenic infection. Rupture of the HHC into the biliary tract is one of the most serious complications and is frequently related to overenlargement of the cyst or major trauma. Patients with this disease usually have jaundice or fever. We report an asymptomatic HHC ruptured after minor trauma. While the ruptured cyst was presented as the subdiaphragmatic gas on the chest radiography, it was detected as a large cyst with multiple daughter cysts on ultrasound, computed tomography scan, and magnetic resonance imaging.
