Imaging features of liver hydatid cyst disseminated into pelvis

Hydatid disease (HD) is a unique parasitic infection that is endemic in many parts of the world. Although the disease primarly affects the liver, HD can be encountered almost anywhere in the body depending on its hematogenous dissemination. In this case report, we describe a 61-year-old man who presented with abdominal pain and urinary complaints. Imaging studies revealed a huge liver and pelvic region lesions that exhibited characteristic imaging findings for type 3 HD.The second lesion was interpreted as occurring due to dissemination from the liver HD. Due to the extensiveness of the disease, both surgery and percutaneous drainage of the lesions were excluded and the patient was put on albendazole treatment.
