Lower extremity weakness Smooth thickening of aortic wall from the descending aorta to the level of just below the renal arteries. The wall thickening shows high signal intensity on T2 and low signal intensity on T1 with subtle intimal enhancement. These findings can suggest possible intramural hematoma. Possibility of atherosclerotic thickening could be lower since the thickening appears to be smooth not irregular. There is normal thoracic kyphosis and lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. The bone marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The epidural space, thecal sac, and spinal cord are preserved with no evidence of spinal canal/neural foraminal narrowing, cord compression, or myelopathy. The conus medullaris terminates at the L1 level.The intervertebral discs demonstrate normal T2 intensity and height with no evidence of disc herniation. The paraspinal soft tissues are unremarkable.There is no evidence of abnormal enhancement, cord compression or mass.
1. Smooth aortic wall thickening from descending aorta to the level of abdominal aorta just below the renal artery. This finding may suggest possible intramural hematoma. Dedicated either CT or MRI examinations for aorta wall evaluation is recommended.2. Normal thoracic and lumbar vertebral bodies and spinal cord.
