Reason: concern for cerebral venous thrombosis History: see MRI brain order - blurry vision, headache, D-dimer elevated and OCP use MRI of the brainNo diffusion weighted abnormalities are appreciated.The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses demonstrate mucosal thickening along the left maxillary sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.Low marrow signal in the visualized osseous structures is non-specific but probably at least in part related to the patient's younger age.MRV brain:The dural venous sinuses are patent. Straight sinus, internal cerebral veins and basal veins are identified and appear patent. The left transverse sinus, sigmoid sinus and jugular vein are larger than their right sided counterparts; this is a a normal variation.
1.No abnormal lesions are appreciated intracranially.2.MR venogram of the brain is within normal limits.
