AbstractInvasive liver abscess syndrome caused by hypervirulent Klebsiella. pneumoniae is a rare disease. This type of K. pneumoniae is aggressive and invasive, despite its sensitivity profile. We report the case of a 62-year-old man with diabetes mellitus, who was admitted to our hospital with meningeal syndrome. Within 24 hours of admission, Gram negative bacilli were isolated blood and cerebrospinal fluid cultures, which were later identified as K. pneumoniae. Liver abscess was detected by computed tomography. Despite early antibiotic treatment, the patient developed back pain that prevented him from moving and right hemiparesis. Increased signal from the central region of the spinal medulla compatible with myelitis was identified by magnetic resonance, for which he received methylprednisolone 1 g/day for 5 days. The patient evolved favorably. Infections caused by hypermucoviscous K. pneumoniae are aggressive and invasive, and more common in men with a history of diabetes mellitus, as in this case. These infections require early antibiotic treatment and the search of metastatic infections.
