Secondary malignant neoplasm of brain [C79.31], Reason for Study: ^Reason: RCC to brain; history of RT to brain; now with new brain met; MRI for RT planning History: RT planning Motion artifact degraded image quality.Previously demonstrated enhancing nodule with the surrounding edema located at the right inferior parietal lobule close to the distal portion of intraparietal sulcus, is unchanged since prior scan (measured about 8mm on 3D SPGR sequence). There are also susceptibility artifacts on the right inferior parietal lobule which again unchanged since prior scan.There is no other abnormal enhancing lesion seen on the scan.There is evidence of right parietotemporal craniotomy.The ventricles, sulci and cisterns are unremarkable. The gray-white matter differentiation is normal. The mastoid air cells are clear. Left maxillary sinus retention cyst is seen, unchanged since prior scan.
1. Preoperative localization scan was performed.2. Unchanged the size of the right inferior parietal lobule nodular enhancing lesion and the extent of the surrounding edema since prior scan.3. Unchanged hemorrhagic lesion at the right parietal lobe since prior scan.
