48-year-old male with hyperreflexia. MRI brain:Within the left occipital cortex, there is a region of increased peripheral T2 signal and susceptibility with atrophy within this region. No associated diffusion restriction or enhancement. There is minimal ex vacuo dilatation of the adjacent left occipital horn. There is no evidence of intracranial hemorrhage, mass, or acute infarct. Small chronic left corona radiata lacunar infarct is noted. There is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size. There is no midline shift or herniation. The major cerebral flow voids are intact. Rightward deviation of the nasal septum.MRI thoracic spine:Alignment is anatomic. Vertebral body heights and disc spaces are intact. No abnormal marrow signal. No abnormal signal within the cord. No significant spinal or neural foraminal stenosis. Small bilateral renal cysts.
1.Chronic encephalomalacia in the peripheral left occipital lobe with associated susceptibility is likely related to prior hemorrhage/trauma or other insult. Please correlate clinically.2.No significant abnormality in the thoracic spine.
