Reason: new onset prolonged seizure History: prolonged seizure x 1 hour. This exam is limited by motion artifact.The corpus callosum appears thin, but fully formed, without evidence of structural abnormality. The septum pellucidum is present. The lateral ventricles are irregular and undulating in contour, with prominent atria and angular ventricular margins. There is generalized loss of periventricular white matter volume. There is mild patchy periventricular hyperintensity on T2-weighted and FLAIR images.Except for the periventricular regions, myelination is adequate for the patient's age. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. There is no evidence of cortical dysplasia, mass lesions, or migration abnormalities. The temporal lobe structures appear normal. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells appear clear.
1. No evidence of acute hemorrhage, edema, or mass effect. There is no evidence of cortical dysplasia or migration abnormalities.2. Constellation of findings is suggestive of periventricular leukomalacia.
