OBJECTIVE
Cerebral abscesses are focal suppurations of infectious origin developed within the cerebral parenchyma. This is a rare pathology, with a relatively poor prognosis. Therapy continues to be debated and the results are inconsistent. The objectives of this study were to define the factors influencing prognosis.
METHODS
In a search for predictive factors, we analyzed 80 observations of intracranial abscesses compiled between January 1990 and December 2004.
RESULTS
We noted a strong male prevalence (7:1) with age ranging from three to 65 years. The duration of symptoms was short in 34 patients (42.5%). A motor deficit existed in 25 cases (31.25%), aphasia in five patients, and seizure in 11. A CT scan in 77 patients and MRI in three patients provided the diagnosis in all patients. The supratentorial location was found in 72.5% of the cases. Otitis ranked first among etiologies, followed by cranial injuries and sinusitis. The pathogenic agent found in the pus from the abscess was seldom found at the entry point. Staphylococcus aureus was found in 12.1% of the cases, followed by Proteus (11.8% of the cases). Seventy-eight patients underwent surgery, two were treated with antibiotics only, with favorable progression in 76.3%. We noted a 13.1% rate of complications and five deaths.
CONCLUSIONS
Comparing the data from this study with those of the literature, we observed that progression was better among young patients with a mean age of 20-35 years, a good level of consciousness, and supratentorial location.
