[Brain abscess in medical environment, a current problem]

ABSTRACT

Brain abscesses are severe infections with lethal outcome in the case of delay in diagnosis and treatment. The authors report their experience about 30 patients with pyogenic brain abscesses treated between 1989 and 2000. The goal of the study is to analyse epidemiological, clinical and therapeutic aspects of this disease. The sex ratio [MW] was 2,3 and the mean age was 34 years. Predisposing factors were sepsis of adjacent organs [53%] and bacteremia [30%]. The clinical manifestations were fever [83%], headaches [90%] and focal neurologic signs [57%]. CT-scan findings were single lesions in 80% of cases. CT-scan showed a deep ring-enhancing lesion with surrounding edema in 77% of cases. Bacteriological agents in 13 cases [43%] were 4 Staphylococcus aureus, 2 Neisseria meningitidis and 7 negative Gram bacilli. Medical treatment alone was in 77% of cases seven patients benefited from medical and neurosurgical approaches. Death occurred in 10% of cases
