Distant sites of metastatic fallopian tube carcinoma, including humerus, umbilicus, and groin, were clearly imaged with FDG-PET; the surgical-pathologic correlations are presented. In disorders such as ovarian or fallopian tube cancer, where a reliable means of diagnosing persistent or recurrent disease remains elusive, PET scanning offers another approach to this problem. Based on the increased rate of glucose metabolism in tumors, this modality focuses on the biochemical differences between malignant tissues and their normal counterparts in order to demonstrate positive findings on imaging. Potential uses of PET scanning in gynecologic oncology are presented.
