 BRAIN: There is a stable 39 x 50 mm right middle cranial fossa arachnoid cyst associated with mild expansion of the right middle cranial fossa. No definite abnormal white matter T2 hyperintense lesions are seen in the cerebral hemispheres, corpus callosum, or the posterior fossa. At most, there may be a very small focus of T2 hyperintensity adjacent to the right temporal horn, but this is equivocal (see image 34 series 501). A 9 x 6 mm extra-axial dural based enhancing nodule is evident along the left postcentral sulcus. This lesion exerts no mass effect on the adjacent parenchyma and is unchanged.The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unremarkable. CERVICAL: There is mild reversal of the normal cervical lordosis. The osseous marrow signal is benign. There are minimal type I degenerative changes at the C6-7 endplates. No worrisome marrow enhancement is detected.Spinal cord signal is within normal limits. There is no abnormal cord enhancement is seen.C2-3: No disk herniation or spinal stenosis.C3-4: No disk herniation or spinal stenosis.C4-5: Mild facet hypertrophy. No disk herniation or spinal stenosis.C5-6: Disk osteophyte complex effacing the ventral CSF without significant spinal canal stenosis. Bilateral uncovertebral hypertrophy causing no significant neural foraminal stenosis.C6-7. Disk osteophyte complex with ventral CSF effacement without significant spinal stenosis. Mild right neuroforaminal narrowing.C7-T1: No disk herniation or spinal stenosis.The sagittal images show no significant disk herniation or spinal stenosis at T1-2 and T2-3.
1.Questionable T2 white matter lesion along the right temporal horn suspected. No other discrete white matter lesions are identified in the brain.2.A 9 x 6 mm enhancing dural based nodule is evident adjacent to the left parietal lobe most likely representing an incidental meningioma. This lesion is unchanged.3.Stable arachnoid cyst in the right middle cranial fossa.4.No demyelinating lesions are detected in the cervical spine.5.Mild cervical spondylosis is seen as above.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
