29 years, Female, preoperative planning for tumor resection. There is an ill-defined T1 hypointense and T2 hyperintense mass in the right frontal lobe without enhancement. The margins of the mass are not well-defined but measures approximately 5.5 x 4.7 x 4.2 cm in the AP, transverse, and craniocaudal dimensions. Signal abnormality extends to the right frontal horn margin and the anterior body of the corpus callosum. Mass is associated with mild leftward subfalcine herniation. There is effacement of the lateral ventricles. No uncal herniation. No hydrocephalus. No additional lesions elsewhere in the brain.
Examination for operative planning demonstrating a right frontal lobe mass most compatible with a glioma. No enhancement, necrosis, or evidence of hemorrhage to suggest a high-grade lesion by imaging.
