Dysarthria [784.51], Reason for Study: ^Reason: SINUS THROMBOSIS History: HEADACHE Brain MRI:No evidence of acute ischemic or hemorrhagic lesion.There are extensive patchy high signal intensity lesions on periventricular white matter on FLAIR images indicate nonspecific small vessel ischemic disease. In addition, there is a slitlike tissue defect on the left basal ganglia with hemosiderin deposition indicating chronic hemorrhagic infarct with encephalomalacia.Right gyrus rectus and right side lower pons also shows encephalomalacia.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. 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.MRV:3D MRV brain Phase Contrast MRV and post-gadolinium with maximum intensity projections of the superficial/deep intracranial venous drainage demonstrate normal superior sagittal sinus, right transverse sinuses, sigmoid sinuses, internal cerebral veins, vein of Galen and straight sinus. The left transverse sinus, sigmoid sinus and jugular bulb appear to be hypoplastic without evidence of intraluminal filling defect or occlusion of venous drainage pathway.
1. No evidence of acute ischemic or hemorrhagic lesion.2. Extensive non specific small vessel ischemic disease with multifocal encephalomalacia as described above.3. No evidence of dural sinus thrombosis.
