the most common cause of congenital hydrocephalus is obstruction of the cerebral aqueduct ?the long, narrow passageway between the third and fourth ventricle. Aqueductal obstruction may result from narrowing or blockage of the aqueduct, or may be caused by infection, hemorrhage, or a tumor. Fluid accumulates upstream from the obstruction, producing hydrocephalus.
