Clinical question: Preoperative planning for tumor resection. Signs and symptoms: Headaches. Pre- and post enhanced Stealth brain MRI:Examination is performed utilizing Stealth protocol and is not a true diagnostic exam. There are also no prior exams for comparison.Examination demonstrates a partially solid partially cystic enhancing mass in the left inferior frontal lobe with fairly extensive surrounding vasogenic edema. Findings results in effacement of adjacent cortical sulci and deviation of midline to the right of approximately 5 mm at the level of septum pellucidum. The tumor measures at 33 x 32 x 30 in three dimensions. Posteriorly the M1 and A1 segment of the middle and anterior cerebral arteries are abutting the tumor however without evidence of encasement. There is no detectable additional foci of signal abnormality or abnormal parenchymal, leptomeningeal enhancement.Calvarium is unremarkable.Images through the orbits are unremarkable.All the paranasal sinuses and bilateral mastoid air cells and middle ear cavities demonstrate normal pneumatization signal pattern.
1.Partially cystic and solid enhancing mass (33 x 32 x 30 mm) in the left paramedian inferior frontal with surrounding vasogenic edema and resultant 5 mm deviation of midline to the right.2.Unremarkable pre and post enhanced Stealth brain MRI exam otherwise.
