BackgroundSubdural empyema (SDE) is a well-known entity in pediatric populations and is associated with a high rate of morbidity and mortality. Large scale evacuation of empyema, although effective, places the bone flap at risk of failure when replaced.Case DescriptionWe report the case of a 19-year-old man with a history of a shunted left middle fossa cyst presenting with a panhemispheric SDE after removal of his cystoperitoneal shunt by an outside facility. Extensive evacuation was performed via the patients prior parietal shunt incision after expansion of the preexisting burr hole. Cultures grew methicillin-sensitive Staphylococcus aureus and Propionibacterium acnes, and he was treated with long-term antibiotics. The patient had a complete recovery with persistent empyema resolution on 6-month follow-up.ConclusionsEndoscopic-assisted burr hole evacuation of large panhemispheric and loculated SDE is feasible, effective, and safe. The primary advantage over conventional open evacuations is that it negates the need for a bone flap and its potential complications related to a secondary infection.Copyright © 2020 Elsevier Inc.
