Ultrasound, CT and MRI of ruptured and disseminated hydatid cysts.

Three cases of echinococcus granulosus with rupture of hydatid cysts and widespread abdominal, pelvic or pleural dissemination are described. Ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) allowed recognition of ruptured hydatid cysts. This assisted to come to an appropriate therapy and exclusion or confirmation of hydatid cysts elsewhere in the body. Ultrasound, CT and MRI are also important for follow-up, evaluation of therapeutic response and/or early diagnosis of recurrence.
