Disturbance of skin sensation [782.0], Reason for Study: ^Reason: paresthesia to left arm and left face new onset History: see above. Brain MRINo evidence of acute ischemic or hemorrhagic lesion on the scan.The ventricles, sulci and cisterns are symmetric and unremarkable. There is mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.There is about 12.6 mm x 4 mm sized extra-axial well marginated lesion attached on the inner table of the skull on the right hemisphere indicating possible calcified meningioma without showing any evidence of mass effect toward the adjacent brain structure.C-spine MRIThere is evidence of external fixation using plate and screws between C4-C5.Comparing to prior scan performed on March 4, 2015, kyphotic angulation of upper cervical spine from C2 to C6 appears to be slightly lessened.Previously recognized extensive degenerative changes as well as spinal cord syrinx at the level of C5 and C6-7 do not show any significant interval change.Spinal canal narrowing especially at the level of C4-5 appears to use to be lessened than prior scan.Neuroforaminal stenosis especially on the left side C45 appears to be slightly lessened, however, still shows mild to moderate stenosis.Otherwise no significant interval change in terms of degenerative changes of intervertebral discs of cervical spine since prior scan.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Postoperative status of cervical spine in particular anterior fixation between C4-C5 with interval improvement of 1) upper cervical lordotic angle 2) the degree of spinal stenosis at the level of C45 and 3) the degree of neuroforaminal stenosis at the level of C45 left side.
