Right visual blur and facial numbness, cape-like numbness and burning with gait instability MR brain: No intracranial mass or mass effect. No abnormal enhancement including the brainstem or cranial nerves. No diffusion abnormality. No intracranial hemorrhage. No evidence of hydrocephalus. Unchanged nonspecific prominence of the left occipital horn which may be developmental. Cisterns are patent. Major intracranial vasculature with normal flow voids. Scattered nonspecific periventricular white matter FLAIR/T2 hyperintensity appearing similar to prior study and compatible with mild small vessel ischemic changes. Mild downsloping of the pituitary gland which is otherwise unremarkable. No abnormal enhancement. Mild mucosal thickening of the paranasal sinuses with right maxillary sinus mucous retention cyst. Mastoid air cells are clear. Osseous structures are unremarkable.MR orbits: No mass, signal abnormality or abnormal enhancement in the orbits. Optic nerves appear normal. No periorbital or retro-orbital soft tissue swelling.MR cervical spine: Spinal cord has a smooth contour without focal atrophy, edema, or myelomalacia. No signal abnormality or mass involving the spinal canal. There is abnormal enhancement involving the right C7/T1 neural foramen which is inseparable from the right C8 dorsal root ganglion. This was suboptimally evaluated previously but appears unchanged since 9/10/2014.Vertebral body heights are maintained. Alignment is maintained. Marrow signal is benign. Multilevel degenerative changes are seen including loss of disc height at C6/7 level. Individual levels as below:C1/2: No significant spinal canal stenosis or foraminal narrowing.C2/3: No significant spinal canal stenosis or foraminal narrowing.C3/4: Uncovertebral hypertrophy with left facet arthropathy resulting in mild to moderate left foraminal narrowing. No significant spinal canal or right foraminal stenosis.C4/5: No significant spinal canal stenosis or foraminal narrowing. C5/6: Mild posterior disc osteophyte. No significant spinal canal stenosis or foraminal narrowing. C6/7: Disc osteophyte complex resulting in minimal narrowing of the spinal canal. No significant foraminal narrowing. C7/T1: Abnormal enhancement involving the right C7/T1 neural foramen as mentioned above. No significant left foraminal or spinal canal stenosis.
1.No significant intracranial abnormality. Specifically, no lesions or abnormal enhancement involving the brainstem, cranial nerves, or orbits. 2.Minimal periventricular white matter foci of FLAIR/T2 hyperintensity, which appears similar to prior study and compatible with mild chronic small vessel ischemic changes.3.There is abnormal non expansile enhancement involving the right C7/T1 neural foramen which is inseparable from the right C8 dorsal root ganglion. Finding was suboptimally evaluated on most recent study but is unchanged dating back to outside MRI from 9/10/2014 and may represent a small nerve sheath tumor. Other etiologies such as a chronic inflammatory process limited to this region seems less likely. No cord signal abnormality or lesions within the spinal canal.
