Pseudotumor Cerebri Support Group
Pseudotumor cerebri (PTC) is a neurological disorder that is characterized by increased intracranial pressure, in the absence of a tumor or other diseases affecting the brain or its lining. Diagnosis requires brain scans and lumbar puncture. Characteristic symptoms are headache, transient visual obscurations or transient visual loss in one or both eyes usually lasting...
At my first Neurology Appt I went to a Neurologist that mostly deals with PTC. I had also been diagnosed through my Ophthalmologist who had ran various eye test but he also had me complete and MRI of the brain with and without contrast which was also one of the first questions my Neurologist asked me about; to me that seems to be the first important step. Then my Neurologist said he wanted me to have a lumbar puncture to verify further the PTC diagnosis and see how high my pressure is. My neurologist explained to me that papilledema is one of the more serious symptoms of PTC because it can make you go blind rather quickly if left untreated. I had my reflexes checked as well as my vision, and a cognitive recognition test. The assistant took my blood pressure and my measurements and they asked me my weight (which unknown to me I gave them a much lower one then what I started out at UGH!) I am about to have my lumbar puncture with an MRA and MRV next Thursday to check my pressure how quickly it builds up and also if I have a blockage that could be causing my pressure to be high. PTC does not have a known cause my Neurologist explained to me that there is always dual causes that mix to cause PTC and finding them to treat them is the difficult part.
I assume that they will send you for an MRI first, then for the LP. Like you, I was pretty nervous about the whole thing, but it really is better to know what you're up against. And as far as the LP goes, I asked if they could give me something mild for my anxiousness, and they did. The procedure was surprisingly painless for me (the radiologist who performed my LP was great), but it was the headache I got afterwards that was bad. As everyone here can tell you, you really do need to stay completely flat for 24 hours after the LP. This will help to prevent you from getting a leak, which causes the terrible headache.
Good luck at your appointment next Thursday - and keep asking questions here, so that you'll know what to ask when you see the doctor. Take notes while you're with the doctor, because you will forget the things you are told. If possible, have someone go with you - two sets of ears to hear all the info are better than one.
Bottom line: You are our own best advocate! Ask what you need to ask and do what you need to do to take care of yourself.
The difference is the level of detail in the scan itself. MRIs have the most detailing of the internal body than any other scan, it is also the most expensive thats why they usually will order a CT first. The difference with and without contrast also gives more depth in the picture that the radiologist is able to see. For instance in a non contrast scan they can see that there are not masses, in a contrast scan they are more able to see if there is a blockage of any type.
