[Sinus pericranii associated to spontaneous thrombosis of the ophthalmic vein: neuroimaging studies].
Sinus pericranii is an abnormal venous communication between the intracranial dural sinuses and epicranial venous dilatations. The periorbital location is uncommon; spontaneous partial thromboses of the subcutaneous varices have been reported in association with local signs and symptoms; however, to our knowledge there are no reports of sinus pericranii associated to thrombosis in the ophthalmic vein. Sinus pericranii is related to arteriovenous and lymphatic-venous malformations. We present the case of a patient with a generalized and diffuse disorder of venous drainage that affected the right cerebral hemisphere who presented at the emergency department with ophthalmologic signs and symptoms after thrombosis of the superior ophthalmic vein and who had three sinus pericranii located in the frontal, parietal, and occipital areas.
