 MRI brain: There are no areas of abnormal signal. There is no diffusion abnormality. The ventricles and sulci are within normal limits. The basal cisterns remain patent. There is no midline shift or mass effect. No extra-axial fluid collection is identified.Normal flow-voids are demonstrated in the major intracranial vascular structures. The midline structures and craniocervical junction are within normal limits. The cerebellar tonsils are normal in position. No evidence of Chiari malformation. The CSF flow studies demonstrates normal biphasic flow ventrally and dorsally.MRI spine: There are 7 cervical, 12 thoracic, and 5 lumbar vertebral bodies. The spine is in normal alignment. The vertebral body and disk heights are well-maintained. No worrisome focal marrow signal abnormality is appreciated. The spinal cord is of normal caliber and signal. The distal spinal cord and conus are within normal limits with the conus terminating at the mid L1 level. There is no evidence of tethered cord. No evidence of filar lipoma or other lesions within the spinal canal.There is trace prominence of the central canal throughout the cervical cord, approximately measuring up to 1-2 mm. There is a thoracic syringohydromyelia which extends from upper T5 up to lower T8 levels, measuring up to 4.7 x 5.5 mm in the axial plane at the T6 level. There is trace prominence of central canal in the more distal cord. There is no significant disk bulge, herniation, spinal canal or foraminal stenosis within the spine.Urinary bladder is grossly distended, which is nonspecific.
1. There is syringomyelia involving the thoracic cord extending from upper T5 to the lower T8 levels. There is mild prominence of central canal more superiorly and inferiorly.2. MRI of the brain appears within normal limits. Cerebellar tonsils are normal in position with preserved biphasic CSF flow at the foramen magnum. No findings to suggest Chiari I malformation.3. No evidence of tethered cord.
