Rare Findings of Gallbladder Metastasis From Cutaneous Melanoma on 18F-FDG PET/CT Imaging

Abstract

Abstract We present the imaging findings of a 77-year-old man with a history of malignant cutis melanoma that metastasized to the gallbladder. A restaging 18F-FDG PET/CT scan showed uneven thickening and elevated 18F-FDG uptake in the gallbladder wall. Subsequently, the patient underwent laparoscopic cholecystectomy, and histopathologic findings confirmed the diagnosis of metastatic melanoma of the gallbladder.
