Clinical question: Preop planning for tumor resection. Signs and symptoms: Preop planning. Pre and post enhanced spelled brain MRI:Examination is performed utilizing a Stealth protocol and is not a true diagnostic study. Examination demonstrates a well-demarcated mildly enhancing mass in the left posterior frontal high convexity measuring approximately at 29 x 31 mm in transaxial dimensions. It demonstrates subtle surrounding vasogenic edema and with resultant regional mass effect.There is also evidence of a mass within the superior sagittal sinus at this site with resultant expansion of the sinus. This finding does not demonstrate any definitive continuity with the above detailed mass however this exam is not a complete diagnostic tests and does not include all MRI sequences. Both of these findings were present on prior exam and without significant change.Ventricular system remains within normal size and did maintain midline. There is no convincing evidence of any additional masses.There is evidence of a left sided parietal craniotomy which mildly extends across the midline to the right similar to prior exam.
Mass within the high convexity left posterior frontal and superior sagittal sinus as detailed.
