Original abstract
A 71-year-old female complicating Parkinson disease and diabetes mellitus was admitted to our medical center for urinary tract infection one month after burr hole irrigation and drainage of left chronic subdural hematoma. Klebsiella pneumonia was detected in the bacterial culture of her urine. As antibiotic therapy started, her condition and peripheral white blood cell counts were improved. But consciousness level got worsened and right hemiparesis appeared. A CT scan showed re-accumulation of left subdural fluid so an emergent irrigation was performed. The old hematoma with slightly yellowish, bloody purulent fluid was found and an intracapsular drain was inserted. Klebsiella pneumonia was detected from the bacterial culture of the hematoma. After 10 days, a CT scan showed subdural fluid collection again, so, total hematoma capsule removal was performed. After the operation, her neurological and serological condition improved and she was discharged without any neurological deficits. Klebsiella pneumonia existing urinary tracts rarely infected subdural hematoma cavity via hematogenous dissemination. We must keep in mind this complication may occur when we see compromised host like this case. Total removal of infected hematoma capsule is considered as radical treatment.
