Uterine pseudotumor detected in F-18 FDG PET/CT: dead fetus and intrauterine pregnancy products

F-18 fluorodeoxyglucose-positron emission tomography-computed tomography (F-18 FDG PET/CT) is frequently used in oncology patients. F-18 FDG PET/CT plays an important role in the detection and management of gynecological cancers, as in many different organ cancers. In addition, PET/CT helps the differentiation of benign and malignant gynecological lesions [1]. While evaluating uterine-derived lesions in premenopausal women, fetal and pregnancy-related structures should also be considered, and the patient should be evaluated in the terms of the possible FDG accumulation due to benign changes [2]. We present a case of pseudotumor in uterus with irregular vaginal bleeding and biochemical pregnancy.
