Abstract
OBJECTIVE
Sinus pericranii (SP) is a rare vascular malformation characterized by abnormal communication between the extracranial and intracranial venous systems, usually involving the superior sagittal sinus (SSS) and occasionally, the transverse sinus.
CASE REPORT
A 28-year-old man was presented with a round, fluctuant, nonpulsatile scalp mass in the frontal area near the midline, the size of which changed, depending on his head position. Magnetic resonance imaging showed an extracranial vein extending through a bony defect in the vertex of the skull and draining into the superior portion of the sagittal sinus.
RESULTS
The lesion was completely removed by surgery. The presence of vascular endothelium in the pathologic specimen suggests a congenital or spontaneous origin.
CONCLUSION
SP is a rare vascular malformation that requires surgical or endovascular treatment for the prevention of life-threatening complications.
