Clinical question: History of right sided brain tumor status post biopsy now planning for resection. Signs and symptoms: Preop planning for resection. Pre and post enhanced Stealth brain MRI:Examination is performed utilizing surgical planning/Stealth protocol and is not a complete diagnostic exam.Examination redemonstrate a large, irregular, enhancing and necrotic tumor in the right hemisphere with significant surrounding vasogenic edema, mass effect with mild deviation of midline to the left. There is no significant change other than subtle decreased midline shift.The tumor is very irregular in configuration which makes precise measurements difficult however it measures approximately 35 mm transverse axis and 61 mm in AP axis. It extends inferiorly into the left thalamus and basal ganglia and extends superiorly and posteriorly and reaches the cortex of the right posterior frontal-parietal lobe similar to prior study.
Very large irregular, enhancing and necrotic right hemispheric mass with surrounding vasogenic edema and trace deviation of midline to the left as detailed.
