 Brain MRI:There is a well-circumscribed, 4 mm, T1 hypointense, T2 hyperintense, nonenhancing focus within the pineal gland consistent with simple renal cyst. The ventricles and sulci are normal in size. Lateral ventricular asymmetry is within acceptable limits of normal anatomic variation. 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. 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. There is no abnormal enhancement within the brain. Spine MRI:There is subtle increased T2 hyperintensity involving the anterior aspect of the cord extending from approximately C7 inferiorly to T6 without associated enhancement. There are no osseous dysplasias or stenoses. The conus terminates at an appropriate level. There are no findings of tethered cord or fatty filum.
1.There is subtle increased T2 hyperintensity involving the anterior aspect of the cord extending from approximately C7 inferiorly to T6 without associated enhancement. Given the clinical history of acute onset a sending paralysis, this appearance can be seen in the clinical setting of Guillain Barre.2.4 mm simple pineal cyst, otherwise negative brain MRI.
