Syncope and collapse [R55], Reason for Study: ^Reason: Transient right side weakness with right arm tremor question TIA vs seizure History: Above Brain MRI:There is no evidence of acute ischemic or hemorrhagic lesion on the scan.There is no evidence of abnormal enhancement.There is tubular susceptibility lesion about 7.4mm in length on the left caudate head which may indicate prior hemorrhagic foci or partially visualized venous structure, no change since prior scan.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, 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.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.Neck MRA:3D TOF MRA of neck and 3D 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. No evidence of acute ischemic or hemorrhagic lesion.2. Tubular susceptibility lesion on the left caudate head likely represent either old hemorrhagic foci or partially visualized venous structure, no change since prior scan.3. Normal Brain MRA and Neck MRA
