Diagnosis and management of occult non-missile penetrating brain injury.

Abstract

Penetrating brain injury (PBI) is a subtype of traumatic brain injury (TBI) that has been steadily increasing in prevalence and causing significant mortality in trauma patients. In an emergent setting, it is important to determine the mechanism of injury and decide whether a PBI or a blunt TBI has occurred in order to guide diagnostic imaging and subsequent treatment. In cases where a PBI has been likely or has occurred, it is important to initiate treatment expeditiously as rapid interventions have been shown to lead to better outcomes. However, in cases of unwitnessed pediatric trauma, it can be difficult to ascertain the specific method of injury due to a lack of reliable sources. In such cases of unwitnessed trauma, PBI should be included in the differential of any orbitocranial injury. In this series, we present two cases of unwitnessed pediatric orbitocranial injury that highlight the importance of gathering a detailed history, obtaining appropriate imaging studies, and using physician intuition.
