Sinus pericranii is a rare vascular anomaly involving an abnormal communication between the extracranial and intracranial circulations. A case of frontal sinus pericranii is presented which appeared to be a posttraumatic sinus because it developed 2 years after a cranial injury. However, the presence of vascular endothelium in the pathological examination and its association with a vascular anomaly (persistent trigeminal artery) suggested a congenital origin. The lesion, pericranial blood sinuses, and bone were totally removed. The computerized tomography, angiography, and magnetic resonance imaging findings are presented. The literature is reviewed and the pathogenesis of sinus pericranii is discussed.
颅骨膜窦是一种罕见的血管异常，涉及颅外和颅内循环之间的异常交通。本文报告一例额部颅骨膜窦病例，因其在颅脑损伤2年后出现，似乎为创伤后形成的窦。然而，病理检查中血管内皮的存在及其与血管异常（持续性三叉动脉）的关联提示其为先天性起源。病变、颅骨膜血窦和骨质被完全切除。文中展示了计算机断层扫描、血管造影和磁共振成像的结果。对相关文献进行了综述，并讨论了颅骨膜窦的发病机制。
