Meningiomas represent the most common benign intracranial neoplasm in adults, with a considerably lower incidence in children. The authors present the case of an intracranial meningioma with invasion of, and intraluminal extension into, the transverse and sigmoid sinuses, jugular bulb, and internal jugular vein, resulting in venous occlusion in a 14-year-old girl. Computed tomography scanning, MR imaging, and conventional angiography were performed preoperatively. The patient underwent a 2-stage resection: the supratentorial component was resected first, and the infratentorial and venous sinus and jugular vein components were subsequently removed using a combined skull base approach. Gross-total resection was achieved by opening the lateral dural sinus and removing the meningioma from within the transverse and sigmoid sinuses, the jugular bulb, and the internal jugular vein. The patient remained neurologically intact after the staged tumor resections. Postoperative imaging confirmed the gross-total resection. This case illustrates the unusual property of an intracranial meningioma to invade the intrasinusoidal space and extend into the jugular vein without adherence to the underlying venous endothelium of the jugular vein.
