Occult Mediastinal Yolk Sac Tumor Producing α-Fetoprotein Detected by 18F-FDG PET/CT

Abstract: Malignant mediastinal yolk sac tumor (YST), especially adult onset, is rare. Herein, we report a case of occult mediastinal YST with α-fetoprotein production revealed by 18F-FDG PET/CT in a young adult, in which the intense tracer uptake was demonstrated in the anterior mediastinum. This case indicates 18F-FDG PET/CT may be a useful tool for detecting the occult primaries of YST.
