Male, 15 years old, with multiple sclerosis. Assess for progression or new inflammatory activity. Brain:Approximately 10 T2 hyperintense lesions are seen within the brain. Most are supratentorial and several involve the periventricular white matter or are radially oriented with respect to the ventricles. One or two small lesions are seen within the cerebellum. All of these lesions were evident on the prior examination and they are either stable or decreased in size. In particular, the dominant left periatrial lesion has decreased significantly in size, and a previously demonstrated lesion at the cervicomedullary junction is no longer detectable. No new lesions are seen. There is no pathologic intracranial enhancement. No areas of significant edema or mass effect are detected. Brain parenchymal volume is preserved. No evidence of intracranial hemorrhage or any abnormal extra axial fluid collection is seen. Ventricular size and morphology are within normal limits.Thoracic spine:No evidence of any focal spinal cord lesion is seen. Within the limitations of motion degradation, no pathologic spinal cord or leptomeningeal enhancement is observed. No epidural lesions are suspected. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. Marrow signal characteristics are unremarkable. Mild disc bulging has developed at T6-7, T7-8 and T8-9. However, there is no significant associated spinal canal or foraminal stenosis.
1.Multiple lesions are identified in the brain compatible with demyelinating disease. When compared to the prior examination, lesions are either stable or decreased in size. No new lesions are seen. No pathologic enhancement is detected to suggest active inflammation.2.A lesion seen previously at the cervico-medullary junction is no longer detectable. Within the thoracic region, no focal spinal cord lesions are identified.
