Malignant neoplasm of brain, unspecified [C71.9] / Encounter for examination for normal comparison and control in clinical research program [Z00.6], Reason for Study: ^Reason: GBM sp/Clinical Investigation History: GBM Right temporal lobe post tumor resection status with the resection cavity is again seen. Measured the size of the resection cavity of the right temporal lobe appears to be unchanged. However, surrounding enhancing tissues show subtle increase since prior scan. In particular, the anterior and mesial aspect of the tumor mass appears to increased since prior scan. And the enhancing lesion on the right side corpus callosum splenium lesion is more conspicuous than prior scan. Effacement of the right lateral ventricle appears to be aggravated since prior scan again indicating increased mass effects.Constellation of above findings indicate possible tumor growth especially anterior and mesial aspect of the resection cavity as well as right side corpus callosum splenium since prior scan.The cranial-cervical junction are normal. The paranasal sinuses are clear.Fluid collections are seen on the right mastoid air cells unchanged since prior scan.
Interval tumor growth especially anterior and mesial aspect of the tumor resection cavity as well as right side of corpus callosum splenium is suspected with increased mass effects toward right lateral ventricle.
