50 years Male (DOB:12/25/1965)Reason: history of RCC to brain s/p resection. History: headachePROVIDER/ATTENDING NAME: STEVEN J CHMURA STEVEN J CHMURA There is redemonstration of status post right-sided craniotomy for right parietal lobe lesion which is associated with susceptibility effect . Compared to the prior exam there is some retraction of the enhancing lesion in the right parietal lobe and evolution of blood products. There is associated contrast enhancement. Since the prior exam associated. Lesional T1 signal hypointensity has regressed but not resolved. Currently the enhancing lesion measures 12 mm whereas previously it measured 18.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is a hemorrhagic lesion present in the right parietal lobe. Changing MR appearance may be attributed to evolution of blood products. A lesion appears smaller in volume on the current versus the prior exam. Continued retraction of the lesion suggests this lesion most likely represents scar formation rather than residual tumor.2.Examination is limited and was performed for treatment planning purposes.
