56 year old man with metastatic renal cell cancer. Concern for new intracranial metastatic lesion. Examination is suboptimal due to extensive motion artifact. There is however noted a very large necrotic tumor in the right frontal lobe measuring approximately 34 mm by 38 mm in transaxial dimension measured on axial image 17. There is approximately 10.3 mm midline shift at the level of the septum pellucidum. This finding is consistent with a metastatic lesion. In addition a focal area of low attenuation in the left posterior parietal is noted which demonstrates no evidence of enhancement. This finding may represent an old stroke. This examination is otherwise unremarkable for an iny additional metastatic lesions. Note however should be made that due to suboptimal quality of the exam secondary to motion artifacts and repeat exam or an MRI is recommended to exclude the possibility of additional metastatic lesions. No evidence of hemorrhage or hydrocephalus is detected.
Large necrotic right frontal lobe tumor believed to represent metastatic lesion from patient's known renal cell cancer. Please see above comments.
