questions about brain abnormality...
What is a brain tumor? How do tumors in the brain differ from lesions, calcifications, cysts, etc?
After experiencing head injury by an ex during a domestic dispute I had a CT scan in the ER and was told I have an unusual 4mm lesion located in the 4th ventricle, possibly Ependynoma or Chorid Plexus. I had to have an MRI for follow-up which showed no abnormalities. However, the radiologist recommended that I have another CT in 3-6 months since the prior CT showed an abnormality.
The radiology tech who performed my 2nd CT told me he has never seen a situation where someone has an abnormal CT but a normal MRI when there is no sign of hemmorage, etc. He assured me that my first CT scan had to have been a false positive. Yet my 2nd CT once again showed an calcified lesion just as the 1st CT scan had said. The radiology report from the 2nd CT does does not recommend additional follow-up. My doctor said I should only be concerned should I become symptomatic.
How can this be? Clearly it is not a big deal, however, I can't help but feel worried. Should I be concerned?
