Anesthesia of skin [R20.0], Reason for Study: ^Reason: Evaluate for ischemia History: LUE and facial numbness Brain MRIThere is focal restricted diffusion on the right thalamus but the lesion already shows FLAIR/T2 high signal intensity indicating possible subacute ischemic infarct. There is no evidence of hemorrhagic conversion.Subtle patchy FLAIR/T2 high signal intensities on bilateral periventricular white matter are nonspecific. The ventricles, sulci and cisterns are unremarkable. There is no mass, mass effect, edema, midline shift, intra or extra-axial fluid collection/hemorrhage. 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.Bilateral P-comm arteries are patent. A common artery is also patent.
