Imaging findings of melanoma metastasis in the gallbladder

We present the case of a 40-year-old male with a previous diagnosis of cutaneous melanoma in the dorsal region, with metastases in axillary and mesenteric lymph nodes and in the central nervous system. He presented focal areas of increased radiopharmaceutical uptake in the topography of the gallbladder infundibulum on a control positron emission tomography/computed tomography (PET/CT), which corresponded to a nodular lesion in an abdominal ultrasound.
