Ct scan results / corpus callosum

[MDeStef84]

I had a CT scan done on 9/3/2010 due to some bad headaches and vision problems I was having. The report findings on that day are : Examination with multiple transverse sections shows symmetrical findings with no mass, hemorrhage, midline shift, or extracerebral collections. The ventricular system is within normal limits. The calvarium is intact. There is no evidence of acute infaction. Impression : Normal findings.

Since 9/3 I've been having a wide variety of symptoms, had 2 different prescriptions given for worsening vision, major headaches, loss of bowel control ONE time after fainting. Lightheadness, dizziness, sensitivity to heat and bright lights, numbness in neck and lower back, also numb on right ankle. And I've lost complete conciousness a few times. There are other symptoms Ive also been having, but I fear I sound like a hypochondriac.

I had a CT scan on 2/26/2011. Findings : Axial CT images of the brain were obtained without contrast utilizing 5mm thin sections throughout, There is a presence of a high riding third ventricle. There is some splyaing and paralleling of the bodies of the lateral ventricles. The findings may reflect a component of corpus callosum agenesis. There is no hydrocephalus. No acute hemmorhage, edema, mass effect or midline shift. Normal gray-white differentiation throughout. Orbits unremarkable. paranasal sinuses and mastiods are clear.

I went to the Neurologist on 3/11/2011. She ordered an MRi of the brain and spine. And a 3 day video monitor EEG. She only reviewed the results of the CT scan that was done on 2/26/2011, I didnt have the other from 9/3/2010 available at the appointment. She told me that the agenisis was a congenital disorder and had nothing to do with ANY of my symptoms, but how can this be congenital if my corpus callosum was seen INTACT on TWo prior CT scans, one was done on 8/2/2008. She tells me rather that I may have low blood pressure and will probably need a referral to a cardiologist if the tests come back inconclusive. I dont understand that considering all of my blood pressure results are usually wonderful, around 142/74. One time I had a low blood pressure reading of 120/57. She also said that she believes I am having seizures. I dont know what in my line of symptoms even comes close to a seizure. I dont seize, or jerk, or move any parts of my body when I get lightheaded. I also dont "stare" into space, or collapse to the ground. I dont understand why she didnt believe me when I told her that I had a CT scan on 9/3/2010 and was never told I was missing a piece of my brain. I dont know if this is completely the wrong forum for me to post in, but im extremely worried and stressed out. And I dont go back for a follow up after my tests until 4/22.

I would appreciate some help and guidance when it comes to these CT results, and any opinion or help would be greatly appreciated. Should I get a second opinion from someone else??? Thank you in advance for your time and help!!!

I looked it up and MRI is the preferred imaging to find the disorder. CTs are good for some things and MRIs are better at others - for this, MRI is better.

I found this:
"Magnetic resonance imaging (MRI) is currently the imaging procedure of choice in infants and children with ACC, even in patients who have previously undergone CT and US examinations. The multiplanar capability and high soft-tissue contrast that are possible with MRI permit confident diagnosis of ACC and its associated anomalies, especially neuronal migration anomalies or atypical forms of holoprosencephaly. These entities may be extremely subtle or indiscernible on CT or US images."

Seizures are apparently a symptom. Seizures can vary greatly. You may want to post this on the neurology forum as well.
