Hydrocephalus can be an emergency if sudden and severe.
Hydrocephalus can be an emergency if sudden and severe. The anatomy of the pathway for CSF drainage includes bottle-necks at the foramina of Monro, the aqueduct of Sylvius, and the foramina of Luschka and Magendie.

The anatomy of the pathway for CSF drainage includes bottle-necks at the foramina of Monro, the aqueduct of Sylvius, and the foramina of Luschka and Magendie. In the Monro Kellie Model the volume of CSF is one Acute hydrocephalus versus chronic hydrocephalus.
If acute hydrocephalus is suspected it is important to make the diagnosis as quidkly as possible. If getting an MRI takes significantly longer than getting a CT to rule out hydrocephalus, get the CT to make sure there is nothing that requires emergency intervention, and THEN more leisurely, get the MRI Making the diagnosis of shunt obstruction is easier in patients with a subgaleal reservoir (usually associated with a VP shunt or Omaya reservoir).

Brain herniation can complicate acute hydrocephalus.
Brain herniation can complicate acute hydrocephalus.
Once intracranial pressure increases enough with respect to the arterial pressure blood flow to and through the brain will decrease enough that cells will start to fail metabolically and ultimately die.
