female, 14 year(s)
 
 
  • Figure 1
    US of multiple hepatic amebic abscesses

    Abdominal Ultrasonography (US) shows a few discrete, hypoechoic foci in the right hepatic lobe with the larger lesions exhibiting a faint posterior acoustic enhancement.

     
    Area of Interest: unknown; Imaging Technique: US of multiple hepatic amebic abscesses;
     
     
  • Figure 2
    CT of multiple hepatic amebic abscesses

    Contrast-enhanced abdominal CT section 3 cm above the porta hepatis reveals the presence of multiple rather well circumscribed hypodense cystic-like lesions disseminated in both hepatic lobes, measuring from a few...

  • Figure 3
    Involvement of terminal ileum in amebiasis

    CT section at the level of the ileocecal valve. A mild circumferential thickening of the terminal ileum wall is shown.

     
    Area of Interest: unknown; Imaging Technique: Involvement of terminal ileum in amebiasis;
     
     
  • Figure 4
    MRI of multiple hepatic amebic abscesses

    Axial T2-weighted image. Presence of multiple foci of high signal intensity, disseminated in both hepatic lobes. Note the presence of a perilesional halo of moderately high signal intensity in the surrounding liver...

  • Figure 5
    Post-contrast MR imaging of multiple hepatic amebic abscesses

    Coronal T1-weighted image 3 minutes after intravenous contrast medium administration. The multiple rounded lesions demonstrate ring-like enhancement.

     
    Area of Interest: unknown; Imaging Technique: Post-contrast MR imaging of multiple hepatic amebic abscesses;
     
     
  • Figure 6
    MR cholangiography

    MR cholangiography shows the cystic lesions and indicates communication with the biliary tree for two of them.

     
    Area of Interest: unknown; Imaging Technique: MR cholangiography;

    CT-guided fine needle aspiration

    CT-guided fine needle aspiration of a peripheral cystic lesion. The fluid was of billous origin and yielded necrotic hepatocytes and white cells but no organisms.

Abdominal Ultrasonography (US) shows a few discrete, hypoechoic foci in the right hepatic lobe with the larger lesions exhibiting a faint posterior acoustic enhancement.
 
Contrast-enhanced abdominal CT section 3 cm above the porta hepatis reveals the presence of multiple rather well circumscribed hypodense cystic-like lesions disseminated in both hepatic lobes, measuring from a few millimeters up to approximately 1,6 cm. The lesions demonstrate peripheral enhancement.
 
CT section at the level of the ileocecal valve. A mild circumferential thickening of the terminal ileum wall is shown.
 
Axial T2-weighted image. Presence of multiple foci of high signal intensity, disseminated in both hepatic lobes. Note the presence of a perilesional halo of moderately high signal intensity in the surrounding liver parenchyma, due to edema.
 
Coronal T1-weighted image 3 minutes after intravenous contrast medium administration. The multiple rounded lesions demonstrate ring-like enhancement.
