  • Figure 1
    Life cycle of E granulosus.

    Humans are the intermediate host of Echinococcus granulosus. Animals that are definitive hosts of the parasite excrete fertilized eggs. Humans eat these eggs and develop hydatidic cysts.

     
    Area of Interest: Abdomen; Abdominal wall; Biliary Tract / Gallbladder; Imaging Technique: CT; Ultrasound; Procedure: Diagnostic procedure; Localisation; Special Focus: Acute; Calcifications / Calculi; Parasites;
     
     
  • Figure 2
    Abdominal ultrasound 1

    Abdominal ultrasound showing a type 2 hydatid cyst. It is round, measures 21cm, and has sharply defined margins. Note that the daugther cyst is arranged on the perphery of the main cyst.

  • Figure 3
    Abdominal ultrasound 2.

    Mother cysts are more echogenic on its central region.

  • Figure 4
    Noncontrast–enhanced axial CT 1

    Large HC with structural deformity, disruption and presence of a fluid collection in the subphrenic space adjacent to the ruptured HC.

  • Figure 5
    Noncontrast–enhanced axial CT 2

    Mother cysts show more radiological density than daughter cysts. Fluid collection in the subphrenic space and invasion of the abdominal wall is also seen.

  • Figure 6
    Noncontrast–enhanced coronal CT

    Partial calcification of the lower part of the cyst.

  • Figure 7
    Noncontrast–enhanced axial CT 3

    Pelvic lesions show similar characteristics to the liver one but they seem more homogeneous and have no mural calcifications.

    Noncontrast–enhanced sagittal CT

    Pelvic lesions show similar characteristics to the liver one but they seem more homogeneous and have no mural calcifications.
