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.
