Learning objectives
• To describe the clinicoepidemiological features of invasive K.
pneumoniae liver abscess syndrome.
• To demonstrate the characteristic imaging findings of liver abscess and accompanying various metastatic infections in invasive K.
pneumoniae liver abscess syndrome.
Background
Primary liver abscess caused by Klebsiella pneumoniae is being reported with increasing frequency in Southeast Asia,
including Korea,
Singapore,
Japan,
and Thailand,
and has become an emerging infectious disease in the United States and worldwide.
It is often complicated by bacteremia,
sepsis,
and metastatic infection of the CNS,
eye,
and other sites,
with the risk being increased in patients with impaired host defenses.
It is called as invasive Klebsiella pneumoniae liver abscess syndrome and the mortality rate has been reported up to 10.8%.

Conclusion
Invasive K.
pneumoniae liver abscess syndrome typically involves patients with underlying systemic diseases such as diabetes mellitus or malignancies,
and often shows multiple liver abscesses and multiple masses or nodules in the lung.
The characteristic clinical and imaging features described in this exhibition can lead radiologists to a possible early diagnosis of invasive K.
pneumoniae liver abscess syndrome.
