Infant Had A Seizure. MRI Showing Possible Frontal Lobe Atrophy. Has Mild Form Of Osteogenesis Imperfecta. Any Advice?

My grandaughter is 3 1/2 months old. All of her developmental benchmarks are met and she is actually a little ahead in her development according to her pediatrician. She had a brief seizure a couple of weeks ago. She was sent for a CT scan which came back as "abnormal" and she is being sent for an MRI for "possible frontal lobe atrophy". Results of her EEG are not back yet. She has a very mild form of osteogenisis imperfecta, but is developing normally in every aspect. What should we expect if she is diagnosed with frontal lobe atrophy?
