[Sinus pericranii: a rare transcranial venous anomaly].
BACKGROUND
Sinus pericranii is a rare midline cranial venous anomaly. It should be diagnosed radiologically. We report an asymptomatic case in a six-year-old female patient.


METHODS
The patient consulted for a congenital asymptomatic bluish mediofrontal swelling. The complaint was strictly esthetic. A color US and MR angiography allowed diagnosing a sinus pericranii. Simple surveillance was decided because of a limited esthetic prejudice and the absence of any functional disorder.


CONCLUSIONS
Sinus pericranii is a communication between extra- and intracranial venous systems. Its diagnosis is suspected when a subcutaneous mass is located on the scalp close to the midline, the volume of which changes with the head's position. It is confirmed by MRI, which usually shows a drainage in the superior sagittal sinus. Surgical treatment is a complex procedure and rarely indicated. A simple follow-up is often proposed because of the usual absence of complications.
