this que is a case frm uw with pseudotumor cerbri and the pt has got bilateral papilloedema but an empty sella on MRI and then it asks for next step in Mx:
LP
trial of prednisone
sumatriptan
refractory testing of eye
sinus x ray
so, of the choices given here, LP is a better one, but do we proceed with LP if the pt has clear fundoscopic findings of papilloedema?
Dear
It seems very logical.The combination of CT/MRI + LP rules out majority of organic causes of ICP,including
- CT/MRI = Tumors LP = infections and SAH
Of course as a therapy ,LP is not a first line therapy in Pseudotumor cerebri but repeated LP are of one of therapy of pseudotumor cerberi.

can we proceed with LP if the pt has got normal CT but bilateral papilloedema?
The answer to THIS question is yes, U can. When U suspect increased ICP (based on papilledema), we do a CT scan to r/o a focal lesion. Once that is ruled out, you can do an LP (even if there is papilledema or other signs of increased CSF pressure) as this pressure is uniformly inceased all over the CSF circulation and therefore there is no risk of herniation. Hope that helps.........
