 BRAIN: Two foci of periventricular T2 hyperintensity are again seen which were present previously. The more posterior lesion has slightly enlarged. There are no new foci of T2 hyperintensity. There is no abnormal enhancement within the brain. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. There is no mass effect or midline shift. The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. The pituitary gland is normal in size. There are no extraaxial fluid collections or subdural hematomas. Flow voids are present within the major vessels indicating patency. The paranasal sinuses and mastoid air cells are clear. CERVICAL SPINE: Alignment is normal. The marrow signal is benign. A previously demonstrated C4-5 intramedullary T2 hyperintense lesion is less conspicuous on this exam. No new lesions and no abnormal enhancement in the cervical spine. The cervicomedullary junction is normal. The cerebellar tonsils are in normal position. The visualized paraspinal contents are unremarkable. No significant spinal canal stenosis or neuroforaminal narrowing of the visualized cervical and upper thoracic spine.
1.Redemonstration of two foci of periventricular T2 hyperintensity which were present previously, one of which is slightly larger. No new lesion or enhancement of the brain.2.A previous C4-5 intramedullary T2 hyperintense lesion is less conspicuous on this exam. No new lesions or abnormal enhancement of the cervical spine.
