Hi,

How are you? Cavum septum pellucidum (CSP) becomes symptomatic due to obstruction of CSF flow. This leads to hydrocephalus and raised CSF pressure.
The treatment is neuroendoscopic fenestration. After surgery the symptoms resolve and can reduce the size of CSP. This procedure can even obviate the need for shunt placement.
If you have already undergone this procedure and symptoms have recurred you may need shunt placement.
I would suggest you to discuss this with your neurosurgeon and let us know if you need more information.
