Limits of 18F-Fluorodeoxyglucose positron emission tomography in recurrence diagnosis of borderline ovarian tumor

Most borderline ovarian tumors (BOT) occur in young women and exhibit a low malignant behavior. Nevertheless, an accurate long-term follow-up is required because, frequently, recurrence arises after many years from primary treatment, especially in patients affected by BOTwith invasive peritoneal implants, which have aworse prognosis.We report the case of a pelvic recurrence of serous BOT firstly suspected by physical examination but misdiagnosed by 18F-fluorodeoxyglucose positron emission tomography and computed tomography and identified only by magnetic resonance imaging, 7 years after primary treatment. We also reviewed the literature concerning the role of 18F-fluorodeoxyglucose positron emission tomography in the management and follow-up of BOT. Copyright © 2010 by IGCS and ESGO.
