Axial T2-weighted MR images (a, c) show numerous abscesses in the liver (arrows) and pylephlebitis in the intrahepatic branches of the main portal vein (arrowheads). Axial diffusion-weighted MR images (b, d) show high signal intensity in the abscesses (arrows) and pylephlebitis (arrowheads) due to restricted water diffusion.

MRI of the abdomen revealed multiple intrahepatic abscesses in addition to pylephlebitis in the intrahepatic branches of the portal vein (Figures 1-2).
Axial (a, b) and coronal (c, d) contrast-enhanced T1-weighted MR images show multiple abscesses (curved arrows) and pylephlebitis in the intrahepatic branches of the main portal vein (arrows), which should not be confused as dilated intrahepatic bile ducts. Notice the normal appearance of main portal vein (arrowheads).

MRI of the abdomen revealed multiple intrahepatic abscesses in addition to pylephlebitis in the intrahepatic branches of the portal vein (Figures 1-2).
(a) Follow-up axial contrast-enhanced T1-weighted MR image shows resolution of liver abscesses and improvement of pylephlebitis with a stricture in the portal branch of the right anterior liver segment (arrowhead), causing inhomogeneous enhancement of the hepatic parenchyma (arrows). (b) No FDG uptake was seen on 18F-FDG PET/CT.

Furthermore, the 18F-FDG PET/CT results showed absence of FDG uptake elsewhere in the body (Figure 3).
