Female, 6 months old, with incidental finding of hypomyelination on previous MRI. Evaluate for interval changes. The pattern of white matter myelination has progressed from the prior examination and falls in the 4 to 5-month-old range. Parenchymal morphology is otherwise unremarkable. The degree of sulcation and gyral development is appropriate. No areas of focal signal abnormality or diffusion restriction are seen. No intracranial hemorrhage or any abnormal extra-axial fluid collection is observed. The ventricles are normal in size and morphology.
Since the prior examination, white matter myelination has progressed and is appropriate for the patient's corrected gestational age. Evaluation of the brain is otherwise unremarkable.
