A 77-year-old male farmer with no significant medical history presented with recently onset jaundice and right upper quadrant pain. a Axial plane postcontrast abdominal CT demonstrates a complex looking mass with heterogenous central part and peripheral calcifications (arrows). Also note dilatation of the intrahepatic bile ducts due to the mass effect of the lesion. b Axial plane T2W MR image demonstrates the cystic nature of the mass (arrows) with internal septations which may suggest detached eccinochocal membrane. There was no evidence of internal contrast enhancement on postcontrast dynamic T1W images (not shown). Percutaneous drainage confirmed hydatid cyst
