 MRI: There is mild prominence of the ventricles and sulci compatible with generalized parenchymal volume loss. There is no midline shift or mass effect. There are scattered areas of high T2 signal in the periventricular and subcortical white matter, as well as what appears to be a punctate focus of encephalomalacia in the left postcentral gyrus. There is no evidence of acute infarction. MRV: The superior sagittal sinus, inferior sagittal sinus, transverse sinuses, sigmoid sinuses, straight sinus, vein of Galen, internal cerebral veins, and several visualized cortical veins are patent. The left transverse sinus is dominant and right transverse sinus is hypoplastic. There is no evidence of venous thrombosis.
1. Probable chronic small vessel ischemic disease and what may represent a tiny chronic infarct in the left postcentral gyrus, but no acute infarct, intracranial hemorrhage, or mass.2. Hypoplastic left transverse sinus is dominant and right transverse sinus, but no evidence of dural venous sinus thrombosis.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
