Bacterial Brain Abscess Caused by Klebsiellae Pneumoniae in an Adult

Bacterial brain abscess is still a disease that challenges neurosurgeons in its diagnoses and treatment, in both adults and children because of variations in the microbiological features, and altered immune status (for example, due to HIV infection, treatment with chemotherapy or organ transplantation). The incidence of brain abscesses is ~ 8% of intracranial masses in developing countries, whereas in the West the incidence is ~ 1–2% [Moorthy, et al., 2008]. Despite a wide spectrum of antibiotics, morbidity and mortality is none the less higher about 27% and 6.612.7% respectively. The overall mortality rate is higher (26.7%) in Klebsiella brain abscess [Liliang, et al., 2001]. It should also be kept in mind that the signs and symptoms of brain abscess can be non-specific, therefore a high index of suspicion is necessary [Lobato, 2009].
