Klebsiella pneumoniae as leading cause of pyogenic liver abscess: Three years study in Southern Vietnam

Figure 4 Multiphase computed tomography images of a pyogenic liver abscess caused by Streptococcus species (white asterisks). The cavity shows slightly irregular margins but homogeneous, non-septated internal architecture with rim enhancement. This contrasts with most Klebsiella pneumoniae liver abscesses, which typically demonstrate heterogeneous internal architecture. A: Non-contrast phase; B: Arterial phase; C: Portal venous phase; D: Delayed phase.
