Invasive Klebsiella pneumoniae syndrome is defined as community-acquired liver abscess and metastatic infections in the lung, soft tissue, and central nervous system (CNS) caused by hypervirulent Klebsiella pneumoniae. Metastatic CNS infection in invasive Klebsiella pneumoniae syndrome shows rapid clinical deterioration and a high mortality rate. We present a case of ventriculitis caused by invasive Klebsiella pneumoniae syndrome successfully treated with a timely diagnosis, immediate surgical intervention, and administration of antibiotics.
