Abstract

A 72-year-old woman who was treated for a poorly differentiated ovarian adenocarcinoma (pT4,M1) underwent FDG-PET/CT scan for suspicion of pararectal disease relapse seen on a CT scan. The pararectal lesion did not show any significant uptake (SUVmax 2.0), but an abnormal unexpected uptake (SUVmax 4.0) was observed in the right pelvic region. A delayed FDG PET/CT scan focused on the pelvic region was performed. On delayed images, the pararectal lesion showed a significant (80%) SUVmax increase (2 vs. 3.6), becoming a clearly positive PET scan. On the other hand, the pelvic lesion showed a stable SUVmax (4.0), but an unchanged anatomic localization of this finding allowing to be differentiated from intestinal activity. Both lesions were confirmed as malignant on histopathological specimens. In conclusion, dual-phase PET acquisition can be helpful in the characterization of an abdominal-pelvic mass.
