Reason: r/o intracranial abnormality History: nystagmus, headache, dizziness The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.There is a punctate T2 hyperintense lesion present along the inferior aspect of the right lentiform nuclei which is hypointense on T1 imaging and does not enhance following contrast administration.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 demonstrate a mucus retention cyst in the left maxillary sinus and a smaller one in the right maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.A small lesion along the inferior aspect of the right basal ganglia is nonspecific. Although most likely this is a benign lesion and of little clinical significance, a follow up exam would help confirm this.
