Parietal sinus pericranii: case report and technical note
1Department of Neurosurgery, Chonnam National University Research Institute of Medical Sciences, Chonnam University Hospital & Medical School, Kwangju, South Korea.
Background:
Sinus pericranii is a rare vascular anomaly that is defined as a group of abnormal communications between the extracranial and intracranial venous systems, usually involving the superior sagittal sinus. Different surgical techniques have been used to manage this anomaly. Surgical technique and radiologic findings are discussed.
Clinical Presentation:
A case of parietal sinus pericranii is presented that was developed spontaneously. This 33-year-old woman presented with a soft fluctuant mass in the right parietal region adjacent to the midline. She complained of headache and dizziness. The preoperative radiologic findings of simple skull X-ray, computed tomography, bone scan, and direct venogram are presented. The lesion was removed completely and then multiple small vascular channels through the underlying skull were obliterated by air-powered diamond drilling. The presence of vascular endothelium in the pathologic specimen suggested a congenital origin.
Conclusion:
We think this method is very easy and useful for managing the multiple small fenestrations of the sinus pericranii without recurrence.
