Clinical question: History of glioneural tumor. Signs and symptoms: Surveillance scan. Pre-and post enhanced brain MRI:Negative diffusion weighted images.Examination demonstrate extensive postoperative changes of a left anterior frontal partial lobectomy removal of tumor. There is resultant significant ex vacuo dilatation of left frontal and of lateral ventricle similar to prior exam. Minimal flair hyperintensity of left frontal lobe immediately superior to the adjacent surgical cavity remains identical to prior exam and consistent with gliosis.Region of flair hyperintensity containing a well demarcated ovoid focus of susceptibility along the interhemispheric right anterior frontal lobe is also again identified and without convincing evidence of interval change. Right there is a very thin rim enhancement surrounding this focus susceptibility. This finding is nonspecific however could represent small focus of postoperative changes, gliosis and chronic blood.Examination is otherwise unremarkable and demonstrate no convincing evidence of any new findings since prior study.
1.Stable examination since prior study and without convincing evidence of any new findings.2.Gliosis surrounding a well demarcated focus of susceptibility along the interhemispheric aspect of right anterior frontal lobe with a thin rim of surrounding enhancement demonstrate no convincing evidence of interval change since prior exam.3.Stable extensive postoperative changes of a larger left anterior frontal lobectomy with out abnormal enhancement since prior exam.
