Slurred speech [R47.81], Reason for Study: ^Reason: stroke protocol History: slurred speech, L facial droop Brain MRIThere is restricted diffusion lesion on the right internal capsule posterior limb without evidence of hemorrhagic conversion.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no mass, mass effect, edema, midline shift. The midline structures and cranial-cervical junction are normal. The mastoid air cells are clear.There is about 10mm (AP) x 7.1mm (RL) x 14mm (CC) sized T2 high signal intensity and T1 low signal intensity lesion on the right side posterior superior and lateral wall of nasopharynx indicating nasopharyngeal polyp. Brain MRA3D time of flight MOTSA MRA brain images with maximum intensity projections of the anterior/posterior intracranial circulation demonstrate no evidence of intracranial arterial luminal occlusion, significant stenosis 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 ischemic infarction without evidence of hemorrhagic conversion on the right internal capsule posterior limb.2. Right side nasopharyngeal polyp [10mm (AP) x 7.1mm (RL) x 14mm (CC) ]3. Normal brain MRA and normal neck MRA.
