Other disturbances of skin sensation [R20.8], Reason for Study: ^Reason: suspect for thalamic lacunar stroke, but autoimmune disorder has some suspicion too, eval pls History: 4d h/o left hemibody hypoesthesia Brain MRIThere is focal restricted diffusion lesion on the right thalamus as well as left side paramedian mid-pons without evidence of hemorrhagic conversion indicating acute/subacute ischemic infarction. There is no evidence acute hemorrhagic lesion.There is no abnormal enhancement.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage, or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. The paranasal sinuses and mastoid air cells are clear.Brain MRA3D 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.Neck MRA3D MRA neck post-gadolinium images with maximum intensity projections of the cervical vasculature demonstrate normal flow enhancement in a normal aortic arch origin of the right brachiocephalic, left common carotid, and left subclavian arteries. The vertebral artery origins are normal. There is normal flow enhancement through the bilateral common carotid, carotid bifurcations, internal/external carotid, and vertebral arteries.
1. Acute/Subacute ischemic infarctions on the right thalamus and paramedian mid-pons without hemorrhagic transformation.2. Normal brain MRA and Neck MRA.
