Hypervirulent Klebsiella pneumoniae (HvKp) is a dynamic pathotype characterized by heightened mucoviscosity and virulence, typically afflicting individuals within the community, who commonly exhibit good health. We presented a case study of a 65-year-old male with diabetes who developed community acquired pneumonia, septic shock, and intracranial infection. The diagnosis was established through cranial magnetic resonance imaging (MRI), typical clinical presentation, and biological culture. The presence of HvKp infection was confirmed by cerebrospinal fluid (CSF) metagenomic next-generation sequencing (mNGS) and blood culture. Treatment consisted of Amikacin 0.8 g qd in combination with meropenem 2.0 g q8h, based on drug sensitivity testing. The patient experienced symptom relief, with the CSF becoming clear and the elimination of the pathogen, ultimately resulting in a successful recovery. The clinical data, diagnosis, and treatment of the patient were documented, and a review of the literature was conducted to offer clinical guidance regarding the intracranial infection resulting from community-acquired HvKp.
