50 years Male (DOB:12/25/1965)Reason: History brain mets s/p SRS. please eval and compare History: NonePROVIDER/ATTENDING NAME: STEVEN J. CHMURA STEVEN J. CHMURA Since the prior exam patient has developed a new lesion located in the right inferior parietal lobule which measures 6 mm in diameter. On the 1/22/2016 exam it measured 2 mm but was partly obscured by patient motion. It is currently surrounded by vasogenic edema.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 no associated contrast enhancement. The visualized portions of the paranasal sinuses demonstrate a mucous retention cyst in the left maxillary sinus.. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.There is a right parietal lobe lesion present which is suspicious for new metastatic disease. 2.There is a hemorrhagic lesion present in the right parietal lobe. Changing MR appearance may be attributed to evolution of blood products. Continued retraction of the lesion suggests this lesion most likely represents scar formation rather than residual tumor.
