Disorientation, unspecified [R41.0], Reason for Study: ^Reason: 26M with hx of PRES, now with intermittent confusion, r/o PRES and venous thrombosis History: intermittent confusion and decreased visual acuity Brain MRINo evidence of acute ischemic or hemorrhagic lesion on 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. 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. There is an accessory salivary gland anterior aspect of the right parotid gland which is partially visualized.MR venogramMotion artifacts degraded image quality.3D phase contrast MRV and 2-D phase contrast MR venogram were performed.Major dural sinuses including superior sagittal sinus, bilateral transverse sinuses, bilateral sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus were visualized. No evidence of major dural sinus or venous drainage pathway occlusion.
1. Normal brain MRI.2. No evidence of venous sinus or major venous drainage occlusion or thrombosis.
