Preoperative planning for right temporal lobe mass. Limited axial images for preoperative stealth planning are provided. There is a T2 hyperintense and T1 isointense peripherally enhancing mass centered in the medial right temporal lobe measuring approximately 3.5 cm. A small amount of surrounding T2 signal consistent with vasogenic edema is demonstrated. There is mild associated mass effect. No midline shift is appreciated. No additional enhancing lesions are identified. The ventricles are nondistended. No extra-axial fluid collections are visualized.There is trace fluid present in the right mastoid air cells. There is diffuse mucosal thickening of the sphenoid sinuses with mild mucosal thickening of the right frontal and ethmoid air cells..
1. Peripherally enhancing mass centered in the medial right temporal lobe measures up to 3.5 cm.2. Paranasal sinus mucosal thickening and trace fluid in the right mastoid air cells.
