 There is significant interval worsening of intracranial tumor burden in the right temporal lobe, as well as new mass in the genu and rostrum of the corpus callosum crossing the midline. There is extensive increased nonenhancing confluent T2 signal abnormality in the right temporal lobe extending into the right periatrial white matter with a significantly larger enhancing mass in the right temporal lobe measuring 28 x 26 mm with a 7-mm exophytic nodule along the anterolateral contour of the mass. There is increased mass effect on the right temporal horn and the right atrium of the lateral ventricles with partial effacement. On the previous exam, the larger mass measured less than 15 mm in maximal dimension. There is a new mass centered in the genu and rostrum of the corpus callosum crossing the midline measuring 10 x 11 mm with associated mild mass effect on the frontal horns. There is mild periventricular and subcortical white matter T2 hyperintensity with involvement of the central pons which is nonspecific, likely representing a combination of small vessel ischemic changes and post treatment changes.There is no acute infarct or midline shift.
1.There is significant interval worsening of intracranial tumor burden in the right temporal lobe, as well as new mass in the genu and rostrum of the corpus callosum crossing the midline.2.Worsened vasogenic edema in the right temporal lobe and mass effect on the right lateral ventricle.Findings were communicated to the Hematology/Oncology Dr. Veneris over the telephone by Dr. Pranay Uppuluri at 3:45 PM today.
