Supplemental Material for: A Bump in the Night: A Case Report of Pediatric Epidural Hematoma Secondary to Sinus Pericranii figshare admin karger (2628495) Pallavi Sai Kapilavaih (25156041) Naina Gross (25156044) Joanna Gernsback (25156047) Medicine Medicine <p dir="ltr">Introduction</p><p dir="ltr">A sinus pericranii (SP) is a rare transcranial vascular malformation caused by diploic emissary veins forming an irregular connection between a dural sinus and extracranial veins. It is generally considered a benign condition with rare complications1. </p><p dir="ltr">Case Presentation</p><p dir="ltr">We report the case of a 5-year-old male who sustained a skull fracture from head trauma with subsequent development of an epidural hematoma due to an underlying ruptured SP as the source. Non-contrast computed tomography (CT) confirmed epidural hematoma. Craniotomy for evacuation revealed an emissary venous connection along the skull fracture line consistent with a ruptured SP. The anomalous venous channel was ligated, and the hematoma was evacuated, with good recovery. To the authors’ knowledge, this case represents the only instance of an SP associated with intracranial hematoma.</p><p dir="ltr">Conclusion</p><p dir="ltr">In pediatric patients presenting with a post-traumatic epidural hematoma, especially when the bleeding source is uncertain, undiagnosed vascular malformations such as SP should be considered. Preoperative vascular imaging and intraoperative awareness of this possibility may be important. </p> 2026-10-01T10:59:24Z Dataset Dataset 10.6084/m9.figshare.34043649.v1 https://figshare.com/articles/dataset/Supplemental_Material_for_A_Bump_in_the_Night_A_Case_Report_of_Pediatric_Epidural_Hematoma_Secondary_to_Sinus_Pericranii/34043649 CC BY 4.0
