The appearance of rare ovarian germ cell tumors such as adult granulosa tumor (GCT) on F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) is reported in this article. We present a patient with recurrent GCT and histologically proven intra-abdominal metastases. Most lesions were above PET resolution (>1 cm). local recurrence demonstrated moderate FDG uptake but metastases had variable (none to mild) avidity. Ovarian GCTs are relatively low metastatic potential frequently solid cystic components, which plausible explanations for its uptake. Clinicians should be aware phenomenon the false negatives FDG-PET.
