Malignant neoplasm of brain, unspecified [C71.9], Reason for Study: ^Reason: Eval GBM. History: GBM. Prior ICH. Right temporal intra axial mass with peripheral enhancement is again demonstrated. Comparing to prior scan, maximum diameter of the mass appears to be slightly decreased in size (for example, previously 54mm of AP diameter on axial post contrast scan and now 49.4mm). However, the degree of mass effects appear to be unchanged.In addition, the enhancing rim of the lesion appears to be slightly smoother than before. However, this could also be related to the scan position and slice thickness differences.The enhancement pattern especially regarding ependymal enhancement is again seen, but unchanged since prior scan (lessen than Jan 29, 2016 scan).The right inferior parietal ICH appears to be unchanged in size and MR characteristics since prior scan. The other lesion located in the right parietal lobe just mesial aspect of ICH does not show any significant difference in size and enhancing characteristics.Multifocal periventricular and deep white matter confluent bihemispheric FLAIR high signal intensities are again seen, unchanged.There is no new enhancing lesion or new abnormal FLAIR or T2 signal intensity on this scan. The ventricles, sulci and cisterns are unchanged. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
1. Measurement of the right temporal lobe mass appears to be slightly decreased in size and the pattern of peripheral enhancement has slightly changed since prior scan as described above. 2. However, the degree of mass effects toward adjacent brain parenchyme has not been changed. Right parietal ICH and another enhancing lesion do not show any interval change since prior scan.3. Confluent bihemispheric FLAIR high signal intensity lesions are redemonstrated, unchanged. 4. No new enhancing lesion is seen.
