Clinical question: Surgical planning for craniotomy. Signs and symptoms: Weakness. Pre and post enhanced Stealth brain MRI:Examination is performed utilizing surgical planning protocol and is not a complete diagnostic study.There is a large necrotic and rim enhancing mass in the right mid temporal lobe and extending superiorly into the right basal ganglia. The largest transaxial dimensions of tumor measures approximately at 41 x 33 mm. The mass applies mass effect on the right temporal horn of lateral ventricle and inseparable from the ventricle or the right choroid plexus in the trigone of right lateral ventricle. There is however no detectable ependymoma enhancement of the ventricular wall.Mass effect results in leftward deviation of midline of approximately 7 mm and without evidence of ventriculomegaly. There is no detectable additional foci parenchymal or leptomeningeal enhancement. There is also no detectable calvarial or retro-orbital enhancement.
Necrotic rim enhancing tumor (41 x 33 mm) suspected of GBM in the right temporal lobe with surrounding vasogenic edema and 7 mm leftward midline shift.
