Sinus pericranii is a rare vascular anomaly in which an abnormal communication exists between the extracranial venous system and the underlying dural venous sinus via the diploe of the skull. We describe a case of a spontaneous thrombosis of the sinus pericranii which was located in the right frontal region and presented as a focal, leathery, and noncompressible mass distinguished in character from the typical manifestation of sinus pericranii. In this case, CT, DSA, MRI, MR venography (MRV), and pathologic examination were performed. The CT showed the bone depression in the skull and the MRI demonstrated the mass, but they were not sufficiently sensitive to detect the thrombus. Pathologic examination and MRV were helpful in depicting the thrombus. She underwent a surgical resection, and at the 5-month follow-up there was no evidence of recurrence.
颅骨板障静脉窦是一种罕见的血管畸形，其特征为颅骨板障内存在颅外静脉系统与硬脑膜窦之间的异常交通。我们描述了一例位于右额区的自发性颅骨板障静脉窦血栓形成病例，该病例表现为局灶性、坚韧、不可压缩的肿块，与典型的颅骨板障静脉窦表现不同。在该病例中，进行了 CT、DSA、MRI、MR 静脉造影（MRV）和病理检查。CT 显示颅骨凹陷，MRI 显示肿块，但均不够敏感以检测血栓。病理检查和 MRV 有助于描绘血栓。患者接受了手术切除，随访 5 个月时未见复发迹象。
