Clinical question: Evaluate for progression of GBM in the left temporal lobe. Prior history of surgery and RT. Signs and symptoms: Left temporal lobe GBM. Pre and post-enhanced brain MRI:Examination demonstrates post operative changes of a left anterior temporal and frontal craniotomy for removal of temporal lobe tumor. Expected chronic postoperative changes of a partial resection of the anterior tip of the left temporal lobe demonstrate no significant change since prior exam. Mild residual gliosis immediately posterior to the lobectomy site is again identified and without convincing evidence of change since prior study. Stable mildly expanded left temporal horn of lateral ventricle.Similar to prior exam there is no detectable abnormal enhancement to suggest residual or recurrence of tumor.A few punctate foci of flair hyperintensity remains identical to prior study. There is also a more localized periventricular white matter flair hyperintensity in the left frontal lobe which is likely post treatment/radiation change which has also remained identical to prior exam.Unremarkable and stable pre-and post-enhanced brain MRI otherwise.
1.No evidence of acute or new finding since prior exam.2.Stable post surgical/therapy changes of the left anterior temporal lobe tumor without evidence of recurrence of disease.
