Unspecified disturbances of skin sensation [R20.9], Reason for Study: ^Reason: evaluate for ischemia History: slurred speech, R sided weakness since 9pm 12/1 Brain MRI:No evidence of acute ischemic or hemorrhagic lesion.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia, or abnormal contrast enhancement. 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 4.8 mm cerebellar tonsillar ectopia through the foramen magnum.Brain MRA:3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate normal ICAs, MCAs and ACAs. Vertebrobasilar system appears to be normal.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Mild cerebellar tonsilar ectopia.3. Normal brain MRA
