 Brain MRI:The ventricles and sulci are normal in size. The cerebellar tonsils are in normal position. There are no masses, mass effect or midline shift. The pituitary gland is normal in size. There is no evidence for intracranial hemorrhage or acute cerebral, brainstem or cerebellar infarction. No diffusion-weighted abnormalities are identified. Myelination is appropriate. 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. Lumbar spine MRI:Fat signal material abuts a low-lying conus at the level of L3/4, extending inferiorly through the lumbosacral junction, communicating with subcutaneous fat through a posterior dysraphism of S3, approaching the sacral hiatus. The remainder of the lumbar spine is unremarkable without pathologic enhancement.
