Systemic lupus erythematosus, unspecified [M32.9], Reason for Study: ^Reason: SLE, cognitive difficulties History: SLE, cognitive difficulties Brain MRINo evidence of acute ischemic or hemorrhagic lesion.No evidence of abnormal enhancement on the 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 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. Right ACA A1 segment is hypoplastic and the right Pcom artery is not seen. The left Pcom artery and Acom artery are patent. There is no intracranial arterial aneurysm. No intracranial arterial luminal irregularity or occlusion.Brain MRV3D MRV brain post-gadolinium with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal flow enhancement in the superior sagittal sinus, transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus.
1. No evidence of acute ischemic or hemorrhagic lesion. No abnormal enhancement.2. Normal brain MRA and MRV.
