title: Escherichia coli subdural empyema following subdural hygroma in elderly patient.
abstract: Subdural empyema of the brain is an uncommon disorder that occurs more frequently in children than in adult. Authors report a very rare of subdural empyema following the subdural hygroma after mild head injury. The exact mechanism of infection is not known. However, we have to consider subdural infection as one of differential diagnosis in elderly patient with subdural hygroma when new abnormal density lesion is developed in the subdural space.
