48 years Female (DOB:3/26/1968)Reason: new headaches with position changes please r/o sinus thrombus History: headachesPROVIDER/ATTENDING NAME: JENNIFER M RUSIECKI JENNIFER M RUSIECKI MRI brain:No abnormal enhancing mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.There is a developmental venous anomaly present in the right frontal lobe.The patient status post right parotid surgery.There are several periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.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 are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRV brain:The left sigmoid sinus and left transverse sinus are very small. The left sigmoid groove and left jugular bulb are small. The left transverse sinus is very small.The dural venous sinuses are patent. Straight sinus, internal cerebral veins and basal veins are identified and appear patent.
1.Several periventricular and subcortical white matter lesions are most likely vascular related but are nonspecific. Alternatively examination may include migraines, trauma, vasculitis.2.There is no evidence for venous sinus occlusion. The left transverse sinus appears be hypoplastic and the left sigmoid sinus and the left jugular vein are congenitally small.3.Status post right parotid removal.
