29-year-old female with bilateral lower extremity weakness. BRAIN MRI:No signal abnormalities are seen in the brain to suggest demyelinating disease. The small pineal cyst is again noted. Brain parenchyma is otherwise unremarkable. There is no acute infarct or intracranial hemorrhage. There is no mass-effect or midline shift. There is no abnormal extra-axial fluid collection. There is no abnormal intracranial contrast enhancement. The major intracranial vascular flow voids are preserved. There is a retention cyst in the inferior aspect of the left maxillary sinus. The orbits are unremarkable. There is no destructive skull lesion.CERVICAL SPINE MRI:The study is limited by patient motion.No definite abnormal intramedullary signal abnormality is evident in the cervical spinal cord. There is no definite abnormal contrast enhancement.There is straightening of the cervical spine and minimal disc desiccation but no significant degenerative disease otherwise. There is no spinal canal or neural foraminal stenosis. THORACIC SPINE MRI:This portion of the examination is especially limited due to motion artifact.Previously seen increased T2 signal in the upper thoracic cord is less conspicuous than on prior examination. The increased T2 signal in the mid to lower thoracic cord is again seen. Enhancement is not well assessed. There are no significant degenerative changes throughout the thoracic spine. No spinal or neural foraminal stenosis is evident.There is minimal dependent atelectasis in both lungs. LUMBAR SPINE MRI:There is normal vertebral body height and alignment. The intervertebral discs demonstrate normal height and signal. No abnormal enhancing lesions are appreciated in the lumbar spine. No significant degenerative changes or stenoses are present in the lumbar spine.
1.Note this examination is significantly motion degraded, particularly the thoracic cord sequences. The abnormal signal in the upper thoracic cord is slightly less conspicuous but persists. Extensive abnormal T2 signal in the mid to lower thoracic cord is not appreciably changed. Examination is not adequate to assess for new small lesions in the mid or distal cord. Repeat examination with sedation/anesthesia can be considered as clinically indicated.2.Brain parenchyma appears grossly unremarkable.3.No signal abnormality in the cervical cord is appreciated. 4.No significant spinal canal or neural foraminal stenosis in the lumbar spine. Cauda equina nerve roots also appear grossly unremarkable.
