Female, 14 years old, with complex seizures, evaluate for focal change providing potential explanation. Image quality is degraded on several sequences by motion artifact. Within this limitation, the following observations are made.An ill-defined focus of T2 hyperintensity is seen within the right frontal white matter just superior to the level of the insula (best seen on image 10 series 501, and image 21 series 801). A thin strand of T2 hyperintensity extending peripherally from this lesion to the brain surface, seen on coronal imaging, is favored to represent a sulcus or perhaps a vessel.No other discrete parenchymal lesions are seen. No restricted diffusion, edema or mass effect is detected. There are no findings to suggest acute or chronic intracranial hemorrhage. No abnormal extra-axial collections are seen. The ventricles are normal in size and morphology. The medial temporal lobe structures are symmetric and morphology and signal.
A nonspecific, ill-defined focus of T2 hyperintensity is seen within the right frontal white matter just superior to the level of the insula. The significance of this finding relative to the patient's seizures is uncertain, though some forms of cortical dysplasia or mild migrational anomaly could represent similarly. Follow-up imaging is suggested.
