Subdural empyema is an infection caused by bacteria that inhabit the space between the middle and outer layers of tissue covering the brain. In most cases, subdural empyema stems from an infection that originated elsewhere in the body. In adults and older children, subdural empyema most commonly stems from a sinus infection. In other cases, subdural empyema can stem from an ear infection or blood infection. A head injury or head surgery can also lead to subdural empyema. In younger children and infants, subdural empyema is usually a complication of meningitis.
