Surgical treatment of scaphocephaly with sinus pericranii.

: A 1-year-old female was admitted with a subcutaneous, pulsatile soft mass in the midline parietal region, and abnormal head shape. Fundus examination showed papilledema, suggesting elevated intracranial pressure. Radiological findings showed sagittal suture craniosynostosis with sinus pericranii. Magnetic resonance venography showed that the drainage through the sinus pericranii was not essential for the venous outflow from the brain. The patient underwent surgical resection of the sinus pericranii and total cranial remodeling. Ligation of the stalk-like orifice attached to the superior sagittal sinus with resection of the sinus pericranii and total cranial reconstruction were performed concurrently. The postoperative course was uneventful, and her papilledema resolved. No recurrence of the sinus pericranii has occurred for 3 years. This case describes a unique one-staged operation to treat sinus pericranii with sagittal suture craniosynostosis.
