Clinical question: Preop planning for tumor biopsy. Signs and symptoms: Tumor biopsy. Pre- and post enhanced Stealth brain MRI:Examination demonstrates a round well-demarcated rim enhancing necrotic tumor in the left temporal lobe measuring at 23 x 24 mm in transaxial dimensions without interval change since prior study from 5-4-15. Extensive surrounding vasogenic edema and minimal amount of internal hemorrhage is again identified and without change. Constellation of findings results in regional mass effect and without deviation of midline.
Treatment planning MRI demonstrate a stable left temporal lobe necrotic rim-enhancing tumor measuring at 23 x 24 in transaxial dimensions.
