      Blunt prenatal trauma is known to have consequences to the developing brain, and can result in subdural hematoma (SDH) or epidural hematoma (EDH). The authors present a case of blunt prenatal trauma resulting in a fetal SDH, intraparenchymal hematoma, and intraventricular hemorrhage, and perform a systematic review of the literature. This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Relevant studies (up to April 2016) that reported on cases of fetal SDH or EDH after blunt prenatal trauma were identified from the PubMed database. The primary outcome was fetal mortality, and the secondary outcome was neurological outcome. Fourteen studies were included in the analysis, comprising a total of 14 patients including the present case. The average gestational age at discovery of hemorrhage was 30.1 weeks. Nine mothers were in a motor vehicle collision and 3 were assaulted; the mechanism of injury for 2 mothers was not defined. Twelve patients had SDH, 1 had EDH, and 1 had conflicting reports. Three patients had intrauterine fetal demise, and 3 died in the neonatal period after birth. Three patients had persistent neurological deficit, and 5 were neurologically intact. Fetal SDH or EDH after blunt trauma to the mother trauma is rare and is associated with mortality. However, a significant number of patients can have good neurological outcomes.
