57 years, Male, metastatic renal cell cancer with suspicious brain lesion. There are multiple enhancing lesions throughout the brain consistent with metastatic disease. At least 8 lesions are identified which on axial post gadolinium series 1201 are seen in the left posterior frontal lobe (image 240), left posterior cingulate gyrus (image 239), along the left mid callosal body surface (image 230), right precuneus (image 230), left occipital lobe (image 180), left occipital lobe (image 166), and bilateral occipital lobes (image 124). The largest of these are the left posterior mid callosal body lesion which measures 5 mm in diameter and the right parietal precuneus lesion which also measures approximately 5 mm in diameter. There is mild surrounding edema associated with the lesions. Some of these lesions demonstrate punctate foci of susceptibility compatible with minimal blood products.No abnormal dural or leptomeningeal enhancement. No midline shift or herniation. No hydrocephalus. No evidence of the infarct. Left cerebellar developmental venous anomaly incidentally noted. Major flow-voids are preserved. Minimal paranasal sinus mucosal thickening and small maxillary mucus retention cysts. Calvarium and extracranial soft tissues are otherwise grossly unremarkable.
There are at least 8 enhancing lesions throughout the brain as detailed above consistent with metastatic disease. Lesions measure up to 5 mm in diameter and are associated with mild surrounding edema. No midline shift or herniation. Some of these lesions demonstrate minimal associated blood products.
