Congenital constriction of the foramen of Monro
- 36 Downloads
We report two cases of hydrocephalus in adults. The radiological investigations and direct inspection during surgery in one of the cases indicate that the hydrocephalus is caused in both cases by a benign stricture in the region of the foramen of Monro and that this constriction is congenital. This origin of hydrocephalus has not been reported previously in adults.
