Presentation
Presented with seizure. The previous medical history was unremarkable. Brain MRI was performed for further evaluation.
Patient Data
MRI shows an ill defined right frontal mass which is heterogeneously low signal at T1 and high signal at long TR images associated with mild compression of frontal horn of the lateral ventricle and also mild effacement of the overlying cortex. There is no obvious contrast enhancement and no gross surrounding edema.
Functional MRI scan during motion of the hand demonstrates that the motor cortex is superior to the tumor , and not involved by the tumor. Fortunately, in this patient, language function is controlled by the left side of the brain.(yellow dots represent increased blood flow)
