Clinical question: Bifrontal GBM. Evaluate for tumor grows. Patient on TMZ. Signs and symptoms: GBM. Pre-and post-enhanced brain MRI:Negative diffusion weighted images.Examination demonstrate a focus of flair/T2 hyperintensity involving the cortex and subcortical white matter and left anterior frontal lobe and reaching the left lateral ventricle without significant change in its extent. There is however noticeable interval decrease size of enhancing tumor at this site and post-infused series. In largest transaxial dimensions of enhancing mass in current exam are asked 13 x 7-mm compared to 16.6 x 14-mm size on prior post-enhanced images. There is also revisualization of a small focus of enhancement along the medial aspect of the left anterior temporal lobe measuring at 7.2-mm compared to prior age as study measurement of approximately 7.8 mm. There is complete resolution of surrounding flair hyperintensity vasogenic edema of this lesion since prior exam.No convincing evidence of any additional foci of enhancement.
1.There is interval decreased size of enhancing tumor in the left frontal lobe which measures 13 x 7 compared to prior study measurements of approximately 16.6 x 14-mm. Surrounding flair hyperintensity signal demonstrate no significant change since prior exam.2.Small enhancing tumor in the right superior frontal gyrus demonstrates minimal interval decreased size to approximately 7.2 mm compared to prior study remeasurement of 7.8-mm and with interval complete resolution of its surrounding vasogenic edema.
