Unusual recurrence pattern in peritorcular meningioma--case report.
A 45-year-old female presented with a recurrent peritorcular meningioma. The recurrence was very unusual as the tumor arose from the confluens sinuum and extended to the left jugular bulb completely within the sinuses, obstructing the venous outflow. However, there were no clinical symptoms or neurological abnormalities, due to the development of collateral circulation. The possibility of intrasinus recurrence should always be considered in patients with tumor invasion to sinus walls, even if the patient has no clinical symptoms or neurological abnormalities.
