Sinus Pericranii : A Case Report and the Literature Review

Sinus pericranii is a rare vascular anomaly that's characterized by an extracranial vascular mass with anastomotic connections between the intracranial and extracranial systems via the diploic veins of the skull. Preoperative evaluations for making the diagnosis are important to help prevent unexpected intraoperative bleeding. We report here on a case of surgically treated sinus pericranii in a 20-year-old female following minor head trauma. The clinical manifestations, pathogenesis and managements are discussed, and we also review the relevant literature.
