Clinical question: Preop planning for left tumor removal. Signs and symptoms: Right arm weakness. Pre-and post-enhanced Stealth brain MRI: This examination is performed utilizing the Stealth protocol and is not a true diagnostic exam. Examination is degraded due to extensive motion artifact.Within this limitation the study redemonstrates a large left posterior parietal enhancing necrotic tumor measuring at 40 x 45-mm in transaxial dimensions. Similar to prior exam there is extensive surrounding vasogenic edema and with trace midline shift to the right. There is interval increased peritumoral edema and size of tumor which measured at approximately 32 x 30-mm on prior exam.Poorly visualized enhancement at the site of previously resected tumor surgical site in the right superior temporal gyrus. The overall appearance finding is suggestive of postsurgical change and measuring approximately at 24-mm in transaxial dimensions. Ventricular system remains normal in size and stable since prior study
1.Interval increased size, surrounding vasogenic edema and associated regional mass-effect of a left parietal necrotic tumor as measured above.2.Enhancement at the surgical bed of a previously removed tumor from right superior temporal gyrus.3.Stable normal size of the ventricular system and with only trace deviation of midline to the right.
