55 years, Female, tumor, seizure, examination for surgical planning. Examination is obtained for surgical planning with limited sequences of the brain. There is evidence of prior left frontotemporal craniotomy for biopsy/partial resection with a large peripherally enhancing mass in the left temporal lobe measuring approximately 6 cm x 5.2 cm in the AP and transverse dimensions and approximately 6.2 cm in the craniocaudal dimensions. Surrounding T2 hyperintensity is also seen extending superiorly to involve the insula and left basal ganglia. More infiltrative T2 hyperintensity is noted within the left temporal lobe including medially along the left hippocampus. Blood products within this region are better appreciated on prior complete brain MRI study. Associated mass effect including effacement of the left lateral ventricle which is slightly improved since 12/16/2015. There remains 5 mm rightward midline shift at the level of the foramen of Monro and left-sided uncal herniation. Again seen is left-sided extra-axial collection beneath the craniotomy measuring up to 9 mm in thickness. No hydrocephalus. Diffuse sphenoid sinus opacification again noted.
Examination limited to sequences for surgical planning demonstrating a large enhancing mass centered in the left temporal lobe consistent with high-grade glioma. Mass effect includes effacement of the left lateral ventricle, rightward midline shift, and left-sided uncal herniation.
