Emerging Multiorgan Klebsiella pneumoniae Invasive Syndrome Leading to Septic Shock: A Case Report and Review of the Literature

Klebsiella pneumoniae (K. pneumoniae) is a community-acquired pathogen that typically causes pneumonia and urinary tract infections. Rarely, it can affect other organ systems such as the gastrointestinal tract, as well as the meninges, ears, eyes, and spine. We present the case of a 62-year-old male admitted with septic shock secondary to necrotizing pneumonia and multiple hepatic liver abscesses, which to the best of our knowledge, is the first reported case of multiorgan invasive K. pneumoniae infection, including the presence of a newly recognized syndrome referred as Invasive Liver Abscess Syndrome (ILAS). It is important to maintain both ILAS and K. pneumoniae invasive syndrome (KPIS) in the differential diagnosis, especially in areas of the world with a large number of tourists and immigrants, such as New York City, where the presented case took place.
