We present the case of a 36-year-old premenopausal woman with a background of surgically-treated cervical neoplasm. She underwent a positron emission tomography-computed tomography (PET-CT) for evaluation of the new appearance of abnormal inguinal lymph nodes. The study showed two hypermetabolic nodules in the pelvic region suggestive of corresponding to an implant and to tumor involvement of the lymph node, respectively. After a clinical evaluation and a new PET-CT scan, it was considered that these uptake foci corresponded to physiological activity of the FDG secondary to ovarian activity in a patient with ovariopexy. This article shows the importance of having complete clinical information about the patients before evaluating the studies. We also present a review of the medical literature on the cervical neoplasm and metabolic behavior of the adnexa in relationship with the menstrual cycle of pre-menopausal women.
