Metastatic renal cell carcinoma. [Genitourinary] [Neuroradiology] [CT]

61 year old male, who came in with symptoms of right arm weakness and 3 months of weight loss despite trying to gain weight.

Head CT shows multiple round lesions in the (patient's) left cerebral hemisphere (right side on images), which likely account for the right-sided weakness. These lesions show hemorrhage as well as substantial surrounding brain edema.

A work-up for metastatic disease included a CT of the abdomen/pelvis, which showed the primary mass in the right kidney.
