Metastatic renal clear-cell carcinoma to the gallbladder: A radiologist's perspective.
Renal-cell carcinoma is the most lethal of all urologic malignancies, with a high metastatic potential. Approximately 25% of patients present with stage IV disease, and up to 40% of patients have disease recurrence after nephrectomy. Computed tomography (CT) is an important imaging modality for initial diagnosis and restaging of this patient population. Although extremely rare, clear-cell renal carcinoma has been reported to metastasize to the gallbladder. We present the case of a 50-year-old man who developed clear-cell renal carcinoma metastases to the contralateral adrenal gland and the gallbladder that were detected at initial restaging with CT scan.
