Abstract

Recently, serotype K1 Klebsiella pneumoniae has been a major agent of an invasive syndrome characterized by liver abscess and its metastatic infection. Extrahepatic infection and its characteristics in patients with renal abscess caused by K. pneumoniae are poorly understood, and few cases of central nervous system infection have been reported. This is a report of 80-year-old woman with uncontrolled type 2 diabetes mellitus with renal abscess caused by serotype K1 K. pneumoniae, complicated with ventriculitis despite of appropriate use of antibiotics. Physicians need to be aware of possibility of metastatic infection in patients with serotype K1 K. pneumoniae infection, if they develop neurologic symptom and focus of infection is still present.

Figure

• 

  Figure 1 (A) Computed tomography scan showed multiple ill-defined nodular hypodense lesions in the left kidney (arrow, yellow), suggesting multiple abscess formation. (B) Follow up CT scan showed large abscess in the upper pole of left kidney (arrow, yellow), which has increased in size and outbulged, as compared to the findings of the previous scan.

• 

  Figure 2 MR diffusion weighted image (A) showed high signal intensity in both lateral ventricle, and low apparent diffusion coefficient (B) values, suggesting abscess formation in both lateral ventricles.
