one episode of loss of consciousness concerning for seizure, evaluate for structural abnormality The CSF spaces are appropriate for the patient's stated age with no midline shift. There is a 3 x 5 mm coronal dimension lesion in the subcortical white matter of the right frontal lobe at the level of the inferior frontal gyrus which is bright on T2 and FLAIR MRI imaging and lower signal on T1-weighted imaging. It is also brighter on the SWI imaging. It is not associated with contrast enhancement.No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.The hippocampi are symmetric.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is no convincing evidence for mesial temporal sclerosis on the basis of this exam.2.There is a small right frontal lobe lesion present within the subcortical white matter which is nonspecific in isolation.
