Abstract
Background
Sinus pericranii is a rare, usually asymptomatic condition that is characterized by an abnormal communication between the intra- and extracranial venous drainage pathways. The etiology is unknown but both congenital and post-traumatic etiologies have been proposed. Treatment is primarily surgical but newer minimally invasive endovascular approaches have been reported and is indicated due to cosmesis, hemorrhage, and air embolism.
Illustrative case
We present a case of an 11-month-old boy having sinus pericranii, who was referred for a slowly growing tumor located frontally in the midline on his scalp since 6 months of age. CT-scan with three-dimensional CT (3D-CT) reconstruction and magnetic resonance imaging along with venography was performed which confirmed the diagnosis. Simple surveillance was decided because of a limited esthetic prejudice and the absence of any functional disorder.
Conclusion
The prognosis is nearly always good with a low risk of bleeding. A simple follow-up is often proposed because of the usual absence of complications.
