Preop evaluation of the right parietal brain tumor Scan was performed under pre-operative stealth protocol with fiducial markers attached on scalp.Redemonstration of rim-enhancing right parietal mass, major about 15 x 21 mm, no change since prior scan.Prior surgery related overlying craniotomy site and skull changes do not show any significant interval change.The ventricles, sulci and cisterns are symmetric and unremarkable. There is no midline shift, restricted diffusion/acute ischemia. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
