Malignant neoplasm of brain, unspecified [C71.9], Reason for Study: ^Reason: Grade III glioma. History: glioma Redemonstration of prior right frontal lobe tumor resection cavity is seen, unchanged.Heterogeneous T1 and T2 signal intensity lesions with minimal enhancement on the posterior aspect of the resection cavity are again seen, unchanged in terms of signal characteristics, extent of the lesion and measured the size since prior scan.T2 hyperintensity lesion along the left frontal horn, left frontal encephalomalacia are unchanged. Right cerebral peduncle volume loss and minimal T2 hyperintensity are again seen, unchanged. There is no evidence of new abnormal enhancing lesion on the scan.The ventricles, sulci and cisterns are unremarkable. There is no midline shift, intra or extra-axial fluid collection/hemorrhage, restricted diffusion/acute ischemia. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Stable right frontal resection cavity as well as ill defined heterogeneous signal intensity lesion posterior aspect of the resection cavity, unchanged since prior scan.2. No evidence of new enhancing lesion on this scan.3. No evidence of growing lesion on this scan.
