Amebic liver abscess: An update

Figure 2 Computed tomographic scans showing various spectrum of complicated amebic liver abscess. A: Axial computed tomography (CT) scan showing a contained rupture of an abscess with localized fluid collection in the perihepatic area. There is a thin enhancing rim around the abscess, characteristic of a type II amebic liver abscess (ALA); B: Coronal CT scan of a 54-year-old male showing rupture of the abscess with intraperitoneal fluid collection diffusely spreading throughout the entire peritoneal cavity, indicative of free abscess rupture; C: Coronal contrast-enhanced CT image showing an amebic abscess located in segment VI with long-segment thrombosis in the peripheral branch of the right hepatic vein. Note the triangular hypodense area surrounding the abscess, indicating hypoperfused parenchyma; D: Coronal contrast-enhanced CT image showing a large amebic abscess that has ruptured into the thoracic cavity with loculated pleural fluid collections. Note that the abscess demonstrates ragged edges with indistinct enhancement, characteristic of a type I abscess; E: Sagittal contrast-enhanced venous phase CT image of a patient showing thrombus extending from the ALA into the inferior vena cava; F: Axial CT scan showing a communication of left lobe ALA with the gastric lumen forming a hepatogastric fistula.
