Intracranial infections are serious and life-threatening health problems. They may present as subdural empyemas or intracerebral abscesses. Surgical drainage and subsequent antibiotic treatment is the main technique for a satisfactory clinical outcome. The aims of this study were to present a 10-year intracranial infection series and discuss the surgical characteristics in the light of literature. Fifty-two patients with intracranial infection underwent surgical treatment between 2008 and 2018. Eleven patients were female and 41 patients were male. The mean age was 40.46 years (range 10-75 years). Eighteen patients had intracerebral abscesses, and 34 had subdural empyemas. All patients underwent surgical treatment as well as an antibiotic regimen. No etiological agent was isolated in 29 (56%) cases. Bacterial agents were detected in 20 cases, while fungi were observed in 3 cases. Staphylococci species were the most common agents and were isolated in 8 (15%) cases. Endoscopic aspiration was performed in 3 cases, while surgical drainage and capsule resection via craniotomy was performed in 49 cases. An associated intracranial tumor was diagnosed in 2 patients with brain abscesses. Four (8%) patients died despite surgical and medical treatments. Surgical treatment via craniotomy is an older method, but it is still the best to treat the intracranial infections not only for decompression of the brain but also to attain an accurate diagnosis. The abscess wall should always be histologically examined after surgery to rule out any intracranial tumor.
