Complicated hydatid cyst in a 50-year-old female. Imaging displays a cyst very close to the biliary tract with lobulated margins, showing a loss of intralesional pressure, most probably resulting from a complication of the biliary connection (not found on magnetic resonance cholangiopancreatography). a Axial T2-weighted magnetic resonance imaging. b Coronal 3D magnetic resonance cholangiopancreatography. c and d Axial T1-fat-sat-weighted imaging without and with contrast on portal venous phase
