title: Bilateral frontal sinus pericranii with an intratabular course. A case report.
abstract: Sinus pericranii is a rare venous anomaly, representing a transosseous connection between the intracranial venous system and the epicranial venous system. We present an unusual case of bilateral frontal sinus pericranii in a 12-year-old boy, with associated lacrimation. Instead of the usual short bridging vein between the intra- and extracranial venous circulation, in our case the veins connecting the superior sagittal sinus and the left superior ophthalmic/orbital vein coursed intratabularly over a distance of several centimeters. To our knowledge, such a course has not previously been reported in literature.
