title: Physiologic FDG uptake in the ovary together with an abdominal wall leiomyoma mimicking metastasizing ovarian cancer on PET/CT imaging.
abstract: F-18 fluorodeoxyglucose (FDG)-PET-CT is increasingly used in the management of patients with ovarian cancer. However, there is a considerable overlap in the imaging features of malignant and benign ovarian lesions because physiological FDG-uptake in the ovaries can occur, depending on the menstrual cycle in premenopausal women.We present a case of FDG uptake in the ovary co-occurring with an intensely FDG active tumor of the abdominal wall in a 44-year-old woman. PET-CT findings, together with medical history, raised the suspicion for a metastasizing ovarian cancer. However, histologic examination demonstrated benign findings, namely abdominal wall leiomyoma and an ovarian follicular cyst.
