Klebsiella pneumoniae brain abscess is a rare and severe condition, which requires early detection and aggressive medical and surgical treatment for potential favorable outcomes.
Background Klebsiella pneumoniae brain abscesses are a rare entity and typically present in immunocompromised patients. We present a case of an overall healthy patient who developed a Klebsiella pneumoniae brain abscess in the absence of liver pathology. Case presentation A 46-year-old Vietnamese man with past medical history significant for hypertension presented to the hospital with acute on chronic worsening of altered mental status, personality changes, and gait dysfunction. Initial vitals revealed temperature of 37.1 degrees C, heart rate 87 beats/minute, blood pressure 150/87 mmHg, respiratory rate 18/minute, and oxygen saturation 99% on room air. Physical exam was notable for altered mental status, Glasgow Coma Scale (GCS) score of 14, and right lower facial droop. Cardiopulmonary exam was within normal limits. Head computed tomography (CT) showed a left frontotemporal mass, with subsequent brain magnetic resonance imaging (MRI) revealing a ring-enhancing lesion concerning for a brain abscess. The abscess was urgently drained; however, there was intraoperative spillage into the ventricles. Intraoperative cultures grew Klebsiella pneumoniae, and the patient was maintained on appropriate antibiotics. He developed worsening mental status, septic shock, and cerebral edema requiring decompressive left hemicraniectomy. Computed tomography of the abdomen and pelvis revealed no hepatic lesions. The patient did not improve, and the family elected for comfort measures. Conclusion High mortality is associated with Klebsiella pneumoniae (as opposed to Klebsiella oxytoca) brain abscesses, especially in the setting of intraventricular spread. This case illustrates the need for early detection, and an aggressive medical and surgical treatment approach is required for a potential favorable outcome.
