Hydrocephalus due to acute aqueductal stenosis following mumps infection: report of a case and review of the literature.

An acquired form of hydrocephalus due to aqueductal stenosis developing as a sequela of mumps virus infection of the central nervous system is presented. Percutaneous third ventriculostomy and interventriculostomy (aqueduct cannulation) were performed using a flexible fiberoptic ventriculoscope. The aqueduct was blocked with amorphous material but was cleared with the scope. This is the first case of a fulminant phase of mumps ventriculitis leading to aqueductal stenosis, which has been treated using a ventriculoscope for the first time.
