Sphenopetrosal sinus in a patient with a petroclival meningioma.A, Left common carotid artery injection, venous phase image obtained in a 61-year-old woman who presented with persistent headache reveals sphenotemporal sinus (arrowhead) draining into the transverse-sigmoid sinus junction (arrow).B−D, Axial contrast-enhanced T1-weighted MR images again show a left petroclival meningioma (asterisks) and sphenopetrosal sinuses (arrows) emptying into transverse-sigmoid sinus junction, which is better seen on the right side (arrowhead). 1, superior petrosal sinus; 2, vein of Labbé; 3, occipitobasal vein; 4, posterior temporal vein; 5, middle temporal vein.
