Co-presentation of a subdural empyema and an infected ventriculoperitoneal shunt in an adult patient: A rare complication with review of literature

摘要

Background: The occurrence of a subdural empyema as a complication of a ventriculoperitoneal (VP) shunt infection is rare. Only three articles have been published on this topic. Moreover, the available literature only involves pediatric patients. Case Description: The authors present a 38-year-old male with a preexisting right frontal subdural hygroma that developed into a subdural empyema in the presence of an infected right occipital VP shunt. A brief literature review is provided, and the pathogenesis is discussed. Conclusion: This is the first known report regarding an adult patient with a subdural empyema and a VP shunt infection. Although a magnetic resonance imaging (MRI) brain is not typically ordered during diagnosis of a shunt infection, the authors advocate a low threshold to employ MRI brain to evaluate for other sources of infection, especially in an immunocompromised patient or in a patient with a history of a subdural hematoma or hygroma that can be easily overlook as being stable on computed tomography of head.
