Data regarding presentation, management, and outcomes are limited to case reports and small case series. There are no technical videos detailing the technique for percutaneous embolization. We present the case of a child with an enlarging, symptomatic accessory type sinus pericranii with connection to the torcula, who underwent percutaneous embolization after unsuccessful transvenous embolization. Embolization was performed with 3.4 cc Onyx-34 under live fluoroscopy and serial control superior sagittal sinus venograms . Significant reduction of flow into the sinus pericranii was achieved and the lesion had nearly completely resolved at the 3-week follow-up. Percutaneous embolization of the sinus pericranii is a reasonable alternative to transvenous embolization, but additional data are needed to determine the optimal treatment. The technical details and practical considerations discussed here may help neurointerventionalists adopt this treatment. The video also includes references 1–4 which are relevant to this topic.Video 1 Case presentation and technique for percutaneous embolization of sinus pericranii­ ER -
