Female, 28 years old, with radicular pain and paresthesias. Brain:Several scattered small foci of T2 hyperintensity are seen within the bilateral frontal white matter. The largest of these is on the right and measures up to 2 mm.There is no evidence of restricted diffusion or any parenchymal edema. No pathologic parenchymal or extra-axial enhancement is detected. No findings to suggest intracranial hemorrhage or any abnormal extra-axial fluid collection are observed. The ventricles are normal in size and morphology. The cerebellar tonsils terminate 2 to 3 mm below the plane of the foramen magnum.Bilateral maxillary sinus and ethmoid air cell mucosal thickening is seen.C-spine:Mild reversal of the normal cervical lordosis may be positional. Spinal alignment is unremarkable. Vertebral body height and morphology are within normal limits. No concerning marrow signal abnormality or pathologic marrow enhancement is seen.The spinal cord demonstrates normal signal intensity and morphology throughout. No focal lesions or any pathologic parenchymal or leptomeningeal enhancement is seen.The intervertebral discs are within normal limits. No significant spinal canal or foraminal stenosis is seen.
1.Several very small foci of white matter signal abnormality are seen in the frontal lobes. These are associated with no evidence of edema and no pathologic enhancement. Findings are nonspecific, and in particular, they are not typical for demyelinating disease.2.Cerebellar tonsillar ectopia is seen. This finding is of uncertain significance relative to the patient's presentation.3.Unremarkable evaluation of the cervical spine with no specific findings to account for the patient's symptoms.
