Five year old had an mri due to a seizure. tiny focal area of increased flair signal involving the anterolateral right frontal white matter which is nonspecific however may reflect minimal gliosis... what does that mean? is it a concern?

What other symptoms did this child have besides seizure? Did he (she) have evidence of systemic infection and other neurological symptoms such as lethargy, somnolence, nausea/vomit, etc. Those symptoms can help us to associate with the MRI findings. I would say a thorough discussion with the pediatrician and the neurologist is warranted. It's always a concern when a 5-year-old-child has a seizure.

Gliosis is commonly associated with a variety of brain disorders. The inflammation/irritation of the tissue around a lesion or seizure focus are examples. Please discuss whether there is any brain mass or lesion see on the MRI and whether the scan is sufficient to detect a brain mass or lesion. Seizures are more frequent with a fever and fever control measures while ill are usually advisable.

The tiny area of gliosis may or may not represent a seizure focus and more likely is a coincidental benign lesion. A pediatric neurologist can assist further evaluation and management. Key is risk of future additional seizure activity.
