Abstract
Introduction Spontaneous central nervous system (CNS) infections in children are rare. Treatment involves surgical intervention and antibiotic therapy. We describe a single centre experience of managing this condition in South Wales. Methods We performed a retrospective review of surgically managed cases in our unit for patients under 18 years of age between 2008 and 2018. Data were collected regarding aetiology, location, microbiology examination, treatment and outcomes. Results Twenty-six patients were identified of which 25 case notes were available. Fifteen were male and 10 were female. Median age was 12 years (age range 0.3–17 years). Seven patients (28%) had a burr-hole aspiration and 18 (72%) underwent craniotomy. A second procedure was performed in 10 (40%) and a third procedure in two (8%). Fourteen (56%) had a brain abscess, 10 (40%) had subdural empyema (one was bilateral) and one (4%) had an extradural empyema. Fifteen (60%) had a raised WCC (>11.5 × 109/L) and 22 (88%) had a CRP of >10 mg/L at presentation. Three (12%) patients had a normal WCC and CRP at presentation. Overall, 12 (48%) were secondary to sinus infection, with the most common organism being Streptococcus. Seven (28%) were due to otitis media or mastoiditis, six (24%) had no cause identified. The mean number of CT/MRI scans was 6.7 (range 3–13). The mean follow-up period was 16.7 months (range 1–117 months). At last follow up, 19 (76%) had a GOS of 5, five (20%) had a GOS of 4 and one (12%) had GOS of 3. There were no deaths. Conclusions In Wales, outcomes have improved over time in keeping with other paediatric neurosurgical units in England. Increased availability of imaging resources in our hospital and use of neuro-navigation for all cases in our unit as well as earlier identification of sepsis, communication with microbiologists with dedicated ward rounds and, enhanced identification of causative organisms and contemporary anti-microbials have also contributed towards the improved management of this condition.
