Metastatic renal cell carcinoma, status post laser ablation of a right parietal lobe lesion. There are interval postoperative findings related to right parietal lobe lesion laser ablation with presumed peripheral enhancement surrounding the ablation zone, which measures up to 22 mm, with surrounding edema. There are findings related to prior right parietal craniotomy with low signal in the treatment bed related to chronic blood products, as well as what may represent a punctate focus of enhancement or intrinsic high T1 signal in the medial portion of the treatment bed. There is also a punctate presumably enhancing lesion in the right superior frontal gyrus. The ventricles are unchanged in size.
1. Interval postoperative findings related to right parietal lobe lesion laser ablation with presumed nonspecific peripheral enhancement.2. Findings related to prior right parietal craniotomy with low signal in the treatment bed related to chronic blood products, as well as what may represent a punctate focus of enhancement or intrinsic high T1 signal in the medial portion of the treatment bed, which may represent treatment effects or tumor, but is otherwise incompletely characterized. Follow up via a complete brain MRI my be useful for further evaluation.3. A punctate presumably enhancing lesion in the right superior frontal gyrus may represent metastatic disease.
