Clinical question: History of ET and Parkinson's. Signs and symptoms: Preop planning for DBS. Pre- and post enhanced brain MRI:Examination is performed utilizing surgical planning protocol which is a limited and not a true diagnostic study.Examination demonstrate a slight generalized prominence of cortical sulci and the lateral ventricles for patient stated age without significant change since prior exam. Patchy foci of periventricular and subcortical low-attenuation white matter and suggestive of small vessel ischemic strokes are noted. Post enhanced images demonstrate previously known a small mental venous anomaly in the left basal ganglia and left insular cortex. No detectable abnormal parenchymal or leptomeningeal enhancement. Unremarkable signal intensity of the calvarium, paranasal sinuses and mastoid air cells and unremarkable images through the orbits.
1.Findings suggestive of chronic small vessel ischemic strokes.2.Generalized prominence of cortical sulci and supratentorial ventricular system for age.3.Small left basal ganglia/left insular cortex developmental venous anomaly.
