37 years Male (DOB:10/13/1978)Reason: Source for recurrent intracranial blood? History: siderosis, hearing loww, ataxiaPROVIDER/ATTENDING NAME: JAMES R. BRORSON JAMES R. BRORSON Cervical spine:The cervical vertebral bodies are appropriate in overall alignment and height. The cervical spinal cord has normal signal characteristics and overall morphology. There is siderosis present along the surface of the cervical spinal cord.At C2-3 there is no significant compromise to the spinal canal or neural foramina.At C3-4 there is no significant compromise to the spinal canal or neural foramina.At C4-5 there is no significant compromise to the spinal canal or neural foramina.At C5-6 there is no significant compromise to the spinal canal or neural foramina. There is a mild disc bulge present at this level.At C6-7 there is no significant compromise to the spinal canal or neural foramina.At C7-T1 there is no significant compromise to the spinal canal or neural foramina.The vertebral artery flow voids appear to be intact.Incidental note is made of an arachnoid cyst within the fourth ventricle measuring 26 x 19 mm in sagittal dimensions and this appears to displace the quadrigeminal plate superiorly. The aqueduct of Sylvius is not well visualized.MRI thoracic spine:The thoracic vertebral bodies are appropriate in the overall alignment and height. The thoracic spinal cord has normal signal characteristics and overall morphology. There is no compromise of thoracic spinal canal or exiting nerve roots. There is siderosis present along the surface of the thoracic spinal cord.
1.Siderosis along the spinal cord.2.There appears be large arachnoid cyst within the superior portion of the fourth ventricle which expands the fourth ventricle. The aqueduct of Sylvius is not readily visualized on this exam raising the question of stenosis of the aqueduct of Sylvius. Please note that this is often associated with noncommunicating hydrocephalus. Please correlate with patient's clinical history.
