Renal Cell Carcinoma Metastasis to the Gallbladder Detected by FDG-PET/CT

Abstract

A 62-year-old male presented to the ER with three episodes of diffuse abdominal pain which occurred after eating. He had a history of renal cell carcinoma (RCC), prostate cancer and bladder cancer. FDG-PET/CT scan showed a hypermetabolic soft tissue density within the fundus of the gallbladder. The patient underwent laparoscopic cholecystectomy and surgical pathology revealed clear cell type RCC. This is the first report that features PET/CT imaging to detect RCC metastasis to the gallbladder. Lesions within the gall bladder and their clinical manifestations can be non-specific and PET/CT can help characterize them. RCC metastasis to the gallbladder is very rare but it should be included in the differential diagnosis, especially in patients with a history of RCC.
