Reason: Evaluate for structural lesions History: paresthesias 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.There is a punctate signal hypointensity on susceptibility imaging along the posterior aspect of the putamen of the right basal ganglia.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 right vertebral artery appears to be hypoplastic distally.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 intracranial mass lesion or demyelination to explain the patient's paresthesias.2.A microhemorrhage along the right basal ganglia is of uncertain clinical significance in isolation. It is conceivable that this could be the source of paresthesia. Please correlate with clinical exam.
