F-18 FDG PET/CT detects right atrial and multi-organ melanoma metastases in a 31-year-old man.
Case Report (n=1)
F-18 FDG PET/CT is effective in detecting rare cardiac and gallbladder metastases in patients with malignant melanoma.
May aid detection of rare melanoma metastases; hypothesis-generating and requires prospective validation.
An F-18-fluoro-2-deoxyglucose (F-18 FDG) whole-body positron emission tomography/computed tomography (PET/CT) study was requested with the purpose of staging for a 31-year-old man with a history of cutaneous malignant melanoma surgically removed from the skin of the left supraclavicular area 15 days ago. Mass lesions with increased FDG uptake in the right atrium, gallbladder, right adrenal gland, and subcutaneous tissue in the left side of the abdomen were detected on F-18 FDG PET/CT scan. The patient underwent cholecystectomy and the lesion in the right atrium was removed surgically. The histopathology of the both lesions revealed metastases from malignant melanoma.
