Case in brief
A breast cancer patient undergoing fertility preservation presented for staging with FDG PET/CT, which incidentally revealed bilateral polycystic ovarian enlargement with intense FDG uptake. This finding raised concerns for ovarian malignancy or peritoneal carcinomatosis. However, recognizing the patient's clinical history of recent oocyte retrieval clarified the diagnosis as ovarian hyperstimulation syndrome, preventing misinterpretation as malignancy.
Diagnostic / clinical pearl
Clinicians should consider ovarian hyperstimulation syndrome in the differential diagnosis of adnexal FDG uptake, especially in patients with a recent history of oocyte retrieval.
Why it matters
As more cancer patients pursue fertility preservation, awareness of ovarian hyperstimulation syndrome as a potential imaging pitfall is crucial to avoid misdiagnosis.
