title: Intense FDG uptake in the ovary with painless torsion.
abstract: We report a case demonstrating intense FDG uptake in the ovary, which was diagnosed to be a hemorrhage and congestion due to painless torsion. An asymptomatic retropelvic mass was detected in a 51-year-old female by echography. FDG-PET demonstrated intense uptake in the mass, thus suggesting an ovarian tumor. A resection of the tumor was performed, and histopathological examination revealed hemorrhage and congestion in the ovary due to ovarian torsion. An ovarian hemorrhage due to painless torsion should be considered in the differential diagnosis of intrapelvic masses demonstrating high FDG uptake, even in asymptomatic patients.
