16-year-old male with a abnormality in the frontal area on CT unimpressive on MR. History of amnestic episode questionable history of trauma and seizure. The appearance of the current CT scan versus the prior is slightly different. There are foci of hypodensity present along knee left the superior frontal gyrus and right precentral gyrus subcortical white matter. Relating to the recent MRI it appears that this potentially represents sulcation and volume averaging. AThere is some asymmetry in the size of the sigmoid sinuses right larger than left and attendant asymmetry in the size of the junction of transverse and sigmoid sinuses.The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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.No evidence for acute intracranial hemorrhage.2.Small hypodense foci superimposed on the left superior frontal gyrus and the right precentral gyrus. These were also identified on the previous exam. The possibility of these represent subcortical abnormality cannot be excluded. It's conceivable that these are related to sulcation and volume averaging. These findings were discussed with the clinical service. The MRI performed recently does not confirm this.
