MY MRI results showed small subependymal nodule with the frontal horn of the left lateral ventricle. Specifically, there is a small T2 hypointense nodule arising from the anterior subependymal region of the left frontal horn of the lateral ventricle. This measures 3 mm. There are no other areas of abnormally increased or decreased signal within the brain. A followup MRI of the brain in 6 months' time is recommended. Should I worry? Thank you, Edward
