Whole-body F-18 fluorodeoxyglucose positron emission tomography/computed tomography (a; maximum intensity projection image) shows large complex mass lesion with fluorodeoxyglucose avid solid components and internal septations in the pelvis (b; white arrow) and fluorodeoxyglucose avid enhancing deposits (black arrows in c-e) in the right-sided pleura and along right major fissure as well as low-grade fluorodeoxyglucose avid right pleural effusion

F-18 FDG PET/CT [Figure 1] showed a large complex solid cystic adnexal lesion with internal septations on either side as well as posterior to the uterus, showing increased FDG uptake in enhancing solid components and along septae.
Follow-up whole-body F-18 fluorodeoxyglucose positron emission tomography/computed tomography (a; maximum intensity projection image) shows significant interval reduction in size, extent, and metabolic activity of ovarian mass (b; white arrow) along with near-complete resolution of right pleural and perifissural deposits as well as right pleural effusion (c-e)

The patient received three cycles of NACT (paclitaxel and carboplatin), and subsequent F-18 FDG PET CT [Figure 2] demonstrated significant interval reduction in size, extent, and metabolic activity of ovarian mass along with near-complete resolution of right pleural deposits and effusion, confirming the nature of pleural lesions as metastases from OC.
