title: Persistent falcine sinus associated with obstruction of the superior sagittal sinus caused by meningioma--case report.
abstract: A 72-year-old woman presented with meningothelial meningioma causing obstruction of the superior sagittal sinus (SSS). Magnetic resonance imaging demonstrated the lesion in the left occipital parasagittal region and a linear vascular structure in the posterior falx extending from the vein of Galen to the SSS. Cerebral angiography demonstrated obstruction of the posterior portion of the SSS and venous flow from the bilateral occipital lobes draining into the falcine sinus and then into the vein of Galen. The tumor was subtotally removed with preservation of the falcine sinus and bridging veins draining into the sinus. The falcine sinus is usually obliterated after birth, but may persist into adulthood and be involved in unusual draining patterns.
